Apple Releases Security Updates for QuickTime

Original release date: July 12, 2007

Last revised: --

Source: US-CERT

Systems Affected

Apple QuickTime on systems running

* Apple Mac OS X

* Microsoft Windows

Overview

Apple QuickTime contains multiple vulnerabilities. Exploitation of

these vulnerabilities could allow a remote attacker to execute

arbitrary code or cause a denial-of-service condition.

I. Description

Apple QuickTime 7.2 resolves multiple vulnerabilities in the way

Java applets and various types of media files are handled. An

attacker could exploit these vulnerabilities by convincing a user

to access a specially crafted Java applet or media file with a

vulnerable version of QuickTime. Since QuickTime configures most

web browsers to handle QuickTime media files, an attacker could

exploit these vulnerabilities using a web page.

Note that QuickTime ships with Apple iTunes.

For more information, please refer to the Vulnerability Notes

Database.

II. Impact

These vulnerabilities could allow a remote, unauthenticated

attacker to execute arbitrary code or commands and cause a

denial-of-service condition. For further information, please see

the Vulnerability Notes Database.

III. Solution

Upgrade QuickTime

Upgrade to QuickTime 7.2. This and other updates for Mac OS X are

available via Apple Update.

On Microsoft Windows, QuickTime users can install the update by

using the built-in auto-update mechanism, Apple Software Update, or

by installing the update manually.

Disable QuickTime in your web browser

An attacker may be able to exploit some of these vulnerabilities by

persuading a user to access a specially crafted media file with a

web browser. Disabling QuickTime in your web browser may defend

against this attack vector. For more information, refer to the

Securing Your Web Browser document.

Disable Java in your web browser

An attacker may be able to exploit some of these vulnerabilities by

persuading a user to access a specially crafted Java applet with a

web browser. Disabling Java in your web browser may defend against

this attack vector. Instructions for disabling Java can be found in

the Securing Your Web Browser document.

Cyber Security Tip ST04-015

Understanding Denial-of-Service Attacks

You may have heard of denial-of-service attacks launched against web

sites, but you can also be a victim of these attacks.

Denial-of-service attacks can be difficult to distinguish from common

network activity, but there are some indications that an attack is in

progress.

What is a denial-of-service (DoS) attack?

In a denial-of-service (DoS) attack, an attacker attempts to prevent

legitimate users from accessing information or services. By targeting

your computer and its network connection, or the computers and network

of the sites you are trying to use, an attacker may be able to prevent

you from accessing email, web sites, online accounts (banking, etc.),

or other services that rely on the affected computer.

The most common and obvious type of DoS attack occurs when an attacker

"floods" a network with information. When you type a URL for a

particular web site into your browser, you are sending a request to

that site's computer server to view the page. The server can only

process a certain number of requests at once, so if an attacker

overloads the server with requests, it can't process your request.

This is a "denial of service" because you can't access that site.

An attacker can use spam email messages to launch a similar attack on

your email account. Whether you have an email account supplied by your

employer or one available through a free service such as Yahoo! or

Hotmail, you are assigned a specific quota, which limits the amount of

data you can have in your account at any given time. By sending many,

or large, email messages to the account, an attacker can consume your

quota, preventing you from receiving legitimate messages.

What is a distributed denial-of-service (DDoS) attack?

In a distributed denial-of-service (DDoS) attack, an attacker may use

your computer to attack another computer. By taking advantage of

security vulnerabilities or weaknesses, an attacker could take control

of your computer. He or she could then force your computer to send

huge amounts of data to a web site or send spam to particular email

addresses. The attack is "distributed" because the attacker is using

multiple computers, including yours, to launch the denial-of-service

attack.

How do you avoid being part of the problem?

Unfortunately, there are no effective ways to prevent being the victim

of a DoS or DDoS attack, but there are steps you can take to reduce

the likelihood that an attacker will use your computer to attack other

computers:

* Install and maintain anti-virus software (see Understanding

Anti-Virus Software for more information).

* Install a firewall, and configure it to restrict traffic coming

into and leaving your computer (see Understanding Firewalls for

more information).

* Follow good security practices for distributing your email address

(see Reducing Spam for more information). Applying email filters

may help you manage unwanted traffic.

How do you know if an attack is happening?

Not all disruptions to service are the result of a denial-of-service

attack. There may be technical problems with a particular network, or

system administrators may be performing maintenance. However, the

following symptoms could indicate a DoS or DDoS attack:

* unusually slow network performance (opening files or accessing web

sites)

* unavailability of a particular web site

* inability to access any web site

* dramatic increase in the amount of spam you receive in your

account

What do you do if you think you are experiencing an attack?

Even if you do correctly identify a DoS or DDoS attack, it is unlikely

that you will be able to determine the actual target or source of the

attack. Contact the appropriate technical professionals for

assistance.

* If you notice that you cannot access your own files or reach any

external web sites from your work computer, contact your network

administrators. This may indicate that your computer or your

organization's network is being attacked.

* If you are having a similar experience on your home computer,

consider contacting your Internet service provider (ISP). If there

is a problem, the ISP might be able to advise you of an

appropriate course of action.

Federal Trade Commission Reports Spoofed Email

Original release date: October 30, 2007

Last revised: --

Source: US-CERT

Systems Affected

* Any computer system can be affected when a person is a victim of

social engineering, such as what can occur when malicious code is

inadvertently downloaded from an attachment in a spoofed email.

Overview

The Federal Trade Commission (FTC) is reporting that spoofed email

messages that appear to come from the FTC contain malicious

attachments. If you open one of these attachments you may infect your

computer with a keystroke logger or other malicious code.

Solution

Be suspicious

Exercise caution when opening email messages and attachments. In this

case, the FTC describes the spoofed email as follows:

The spoof email includes a phony sender's address, making it appear

the email is from "frauddep@ftc.gov" and also spoofs the

return-path and reply-to fields to hide the email's true origin.

While the email includes the FTC seal, it has grammatical errors,

misspellings, and incorrect syntax.

Attackers often construct email messages and web sites to imitate

legitimate organizations in order to more effectively convince you to

open and execute malicious attachments or click on malicious links.

See the Avoiding Social Engineering and Phishing Cyber Security Tip in

the references section for more information.

Install and update anti-virus software

Updated anti-virus software can protect you from malicious code. For

more information, please see Cyber Security Tip ST04-005 and ST05-006.

Description

This spoofed email activity relies on social engineering techniques to

convince you to open and run a malicious attachment. There is no

software vulnerability involved and there is no software update to

protect against this type of activity. For more information please see

the FTC report.

National Cyber Alert System

Technical Cyber Security Alert TA07-334A

Apple QuickTime RTSP Buffer Overflow

Original release date: November 30, 2007

Last revised: --

Source: US-CERT

Systems Affected

A buffer overflow in Apple QuickTime affects:

* Apple QuickTime for Windows

* Apple QuickTime for Apple Mac OS X

Overview

Apple QuickTime contains a buffer overflow vulnerability in the way

QuickTime processes Real Time Streaming Protocol (RTSP) streams.

Exploitation of this vulnerability could allow an attacker to execute

arbitrary code.

I. Description

Apple QuickTime contains a stack buffer overflow vulnerability in the

way QuickTime handles the RTSP Content-Type header. Most versions of

QuickTime prior to and including 7.3 running on all supported Apple

Mac OS X and Microsoft Windows platforms are vulnerable. Since

QuickTime is a component of Apple iTunes, iTunes installations are

also affected by this vulnerability.

An attacker could exploit this vulnerability by convincing a user to

access a specially crafted HTML document such as a web page or email

message. The HTML document could use a variety of techniques to cause

QuickTime to load a specially crafted RTSP stream. Common web

browsers, including Microsoft Internet Explorer, Mozilla Firefox, and

Apple Safari can be used to pass RTSP streams to QuickTime, exploit

the vulnerability, and execute arbitrary code.

Exploit code for this vulnerability was first posted publicly on

November 25, 2007.

II. Impact

This vulnerability could allow a remote, unauthenticated attacker to

execute arbitrary code or commands and cause a denial-of-service

condition.

III. Solution

As of November 30, 2007, a QuickTime update for this vulnerability is

not available. To block attack vectors, consider the following

workarounds.

Block the rtsp:// protocol

Using a proxy or firewall capable of recognizing and blocking RTSP

traffic can mitigate this vulnerability. Known public exploit code for

this vulnerability uses the default RTSP port 554/tcp, however RTSP

can use a variety of ports.

Disable file association for QuickTime files

Disable the file association for QuickTime file types. This can be

accomplished by deleting the following registry keys:

HKEY_CLASSES_ROOT\QuickTime.*

This will remove the association for approximately 32 file types that

are configured to open with QuickTime Player.

Disable the QuickTime ActiveX controls in Internet Explorer

The QuickTime ActiveX controls can be disabled in Internet Explorer by

setting the kill bit for the following CLSIDs:

{02BF25D5-8C17-4B23-BC80-D3488ABDDC6B}

{4063BE15-3B08-470D-A0D5-B37161CFFD69}

More information about how to set the kill bit is available in

Microsoft Knolwedgebase Article 240797. Alternatively, the following

text can be saved as a .REG file and imported to set the kill bit for

these controls:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX

Compatibility\{02BF25D5-8C17-4B23-BC80-D3488ABDDC6B}]

"Compatibility Flags"=dword:00000400

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX

Compatibility\{4063BE15-3B08-470D-A0D5-B37161CFFD69}]

"Compatibility Flags"=dword:00000400

Disable the QuickTime plug-in for Mozilla-based browsers

Users of Mozilla-based browsers, such as Firefox can disable the

QuickTime plugin, as specified in the PluginDoc article Uninstalling

Plugins.

Disable JavaScript

For instructions on how to disable JavaScript, please refer to the

Securing Your Web Browser document. This can help prevent some attack

techniques that use the QuickTime plug-in or ActiveX control.

Secure your web browser

To help mitigate these and other vulnerabilities that can be exploited

via a web browser, refer to Securing Your Web Browser.

Do not access QuickTime files from untrusted sources

Do not open QuickTime files from any untrusted sources, including

unsolicited files or links received in email, instant messages, web

forums, or internet relay chat (IRC) channels.

Ok.

Ok, but how can that happen according to this:

"QuickTime does not appear to register itself as the handler

for the RTSP protocol on Windows systems"

Unless because of this:

"Disable the file association for QuickTime file types to help

prevent windows applications from using Apple QuickTime to open

QuickTime files. This can be accomplished by deleting the

following registry keys:

HKEY_CLASSES_ROOT\QuickTime.*

This will remove the association for approximately 32 file types

that are configured to open with the QuickTime Player software.

I suppose the easiest solution is to rename the file "qtplugin.ocx".

Any idea if quicktime alternative is vulnerable?

Yeah, a somewhat misleading comment there... so its just MAC or ...

But when taken with the Apple warning of a month or so ago, Windows seems

to be one to be concerned about as well.

| Unless because of this:

|

| "Disable the file association for QuickTime file types to help

From what appears, that may be an additional fix. I really haven't used

QuickTime for almost a couple years now, so I have no way to test or review

what would or wouldn't work.. though without the OCX at least it wouldn't

apparently load when called via a web page or other.

|

| Any idea if quicktime alternative is vulnerable?

|

| http://en.wikipedia.org/wiki/QuickTime_Alternative

Oh wow, thanks for the link [will look sometime soon]. Perhaps that might

be the next issue to test before I stop doing so [okay, so now the target

end date is January maybe]... never even bothered to look for a replacement

....

Have you tried it yet, e.g. anything to report?

Cyber Security Tip ST07-001

Shopping Safely Online

Online shopping has become a popular way to purchase items without the

hassles of traffic and crowds. However, the Internet has unique risks,

so it is important to take steps to protect yourself when shopping

online.

Why do online shoppers have to take special precautions?

The Internet offers a convenience that is not available from any other

shopping outlet. From the comfort of your home, you can search for

items from countless vendors, compare prices with a few simple mouse

clicks, and make purchases without waiting in line. However, the

Internet is also convenient for attackers, giving them multiple ways

to access the personal and financial information of unsuspecting

shoppers. Attackers who are able to obtain this information may use it

for their own financial gain, either by making purchases themselves or

by selling the information to someone else.

How do attackers target online shoppers?

There are three common ways that attackers can take advantage of

online shoppers:

* Targeting vulnerable computers - If you do not take steps to

protect your computer from viruses or other malicious code, an

attacker may be able to gain access to your computer and all of

the information on it. It is also important for vendors to protect

their computers to prevent attackers from accessing customer

databases.

* Creating fraudulent sites and email messages - Unlike traditional

shopping, where you know that a store is actually the store it

claims to be, attackers can create malicious web sites that mimic

legitimate ones or create email messages that appear to have been

sent from a legitimate source. Charities may also be

misrepresented in this way, especially after natural disasters or

during holiday seasons. Attackers create these malicious sites and

email messages to try to convince you to supply personal and

financial information.

* Intercepting insecure transactions - If a vendor does not use

encryption, an attacker may be able to intercept your information

as it is being transmitted.

How can you protect yourself?

* Use and maintain anti-virus software, a firewall, and anti-spyware

software - Protect yourself against viruses and Trojan horses that

may steal or modify the data on your own computer and leave you

vulnerable by using anti-virus software and a firewall (see

Understanding Anti-Virus Software and Understanding Firewalls for

more information). Make sure to keep your virus definitions up to

date. Spyware or adware hidden in software programs may also give

attackers access to your data, so use a legitimate anti-spyware

program to scan your computer and remove any of these files (see

Recognizing and Avoiding Spyware for more information).

* Keep software, particularly your web browser, up to date - Install

software patches so that attackers cannot take advantage of known

problems or vulnerabilities (see Understanding Patches for more

information). Many operating systems offer automatic updates. If

this option is available, you should enable it.

* Evaluate your software's settings - The default settings of most

software enable all available functionality. However, attackers

may be able to take advantage of this functionality to access your

computer (see Evaluating Your Web Browser's Security Settings for

more information). It is especially important to check the

settings for software that connects to the Internet (browsers,

email clients, etc.). Apply the highest level of security

available that still gives you the functionality you need.

* Do business with reputable vendors - Before providing any personal

or financial information, make sure that you are interacting with

a reputable, established vendor. Some attackers may try to trick

you by creating malicious web sites that appear to be legitimate,

so you should verify the legitimacy before supplying any

information (see Avoiding Social Engineering and Phishing Attacks

and Understanding Web Site Certificates for more information).

Locate and note phone numbers and physical addresses of vendors in

case there is a problem with your transaction or your bill.

* Take advantage of security features - Passwords and other security

features add layers of protection if used appropriately (see

Choosing and Protecting Passwords and Supplementing Passwords for

more information).

* Be wary of emails requesting information - Attackers may attempt

to gather information by sending emails requesting that you

confirm purchase or account information (see Avoiding Social

Engineering and Phishing Attacks for more information). Legitimate

businesses will not solicit this type of information through

email.

* Check privacy policies - Before providing personal or financial

information, check the web site's privacy policy. Make sure you

understand how your information will be stored and used (see

Protecting Your Privacy for more information).

* Make sure your information is being encrypted - Many sites use

SSL, or secure sockets layer, to encrypt information. Indications

that your information will be encrypted include a URL that begins

with "https:" instead of "http:" and a lock icon in the bottom

right corner of the window.

* Use a credit card - Unlike debit cards, credit cards may have a

limit on the monetary amount you will be responsible for paying if

your information is stolen and used by someone else. You can

further minimize damage by using a single credit card with a low

credit line for all of your online purchases.

* Check your statements - Keep a record of your purchases and copies

of confirmation pages, and compare them to your bank statements.

If there is a discrepancy, report it immediately (see Preventing

and Responding to Identity Theft for more information).

Adobe Updates for Multiple Vulnerabilities

Original release date: December 21, 2007

Last revised: --

Source: US-CERT

Systems Affected

* Adobe Flash Player 9.0.48.0 and earlier

* Adobe Flash Player 8.0.35.0 and earlier

* Adobe Flash Player 7.0.70.0 and earlier

Overview

Adobe has released Security bulletin APSB07-20 to address multiple

vulnerabilities affecting Adobe Flash Player. Attackers could exploit

these vulnerabilities to execute arbitrary code, perform DNS rebinding

and cross-site scripting attacks, conduct port scans, or cause a

denial of service.

I. Description

Adobe Security Update APSB07-20 addresses a number of vulnerabilities

affecting Adobe Flash 9.0.48.0 and earlier, 8.0.35.0 and earlier and

7.0.70 and earlier. Further details are available in the related

vulnerability notes.

An attacker could exploit these vulnerabilities by convincing a user

to load a specially crafted Flash file. Flash content is widely

deployed on the internet. An attacker could distribute Flash files

using web sites that allow user-supplied content, like popular social

networking sites.

II. Impact

The impacts of these vulnerabilities vary. An attacker may be able to

execute arbitrary code, perform DNS rebinding or cross-site scripting

attacks, conduct port scans, or cause a denial of service.

III. Solution

Upgrade Flash Player

Upgrade Flash Player according to the information in Adobe Security

bulletin APSB97-20. For the port scanning issue (CVE-2007-4324),

consider ActionScript network socket functionality per TechNote

kb402956.

Adobe provides a way to determine which version of Flash Player is

installed and a way to configure notifications of updates.
