Apple QuickTime contains an integer overflow in handling UDTA atoms, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Apple QuickTime User Data (UDTA) Atoms allow a user to “… define and store data associated with a QuickTime object, such as a movie, track, or media. This includes both information that QuickTime looks for, such as copyright information or whether a movie should loop, and arbitrary information—provided by and for your application—that QuickTime simply ignores.”
Apple QuickTime 7.1.5 addresses an integer overflow in the handling of the size field in UDTA Atoms. Note that this issue affects QuickTime installations on both Apple Mac OS X and Microsoft Windows operating systems.
A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial-of-service condition. The crafted QuickTime media file may be supplied on a web page, in an email for the victim to select, or by some other means designed to encourage them to invoke QuickTime on the exploit file.
Upgrade
This issue is addressed in Apple QuickTime 7.1.5 security document 305149. An update for Mac OS X and Microsoft Windows is available on Apple Downloads and via Software Update.
Disable the QuickTime ActiveX controls in Internet Explorer
The vulnerable 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 Support Document 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 file association for QuickTime files
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.
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.
Do not access QuickTime files from untrusted sources
Attackers may host malicious QuickTime files on web sites. In order to convince users to visit their sites, those attackers often use a variety of techniques to create misleading links including URL encoding, IP address variations, long URLs, and intentional misspellings. Do not click on unsolicited links received in email, instant messages, web forums, or internet relay chat (IRC) channels. Type URLs directly into the browser to avoid these misleading links. While these are generally good security practices, following these behaviors will not prevent exploitation of this vulnerability in all cases, particularly if a trusted site has been compromised or allows cross-site scripting.
