Signature Detail

HTTP: Apple QuickTime QTVR QTVRStringAtom Parsing Buffer Overflow (CVE-2012-0667)

This signature detects attempts to exploit a known vulnerability against Apple QuickTime. It is due to a signedness error, which leads to a stack-based buffer overflow when processing a QTVR string atom having an overly large stringLength parameter. A remote attacker can exploit this vulnerability by enticing a user to download and process a specially crafted QuickTime VR file with the vulnerable software. This can lead to code execution in the context of the vulnerable application.

Extended Description

Apple QuickTime is prone to a remote code execution vulnerability. The issue arises when the application handles specially crafted files. Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts will cause denial-of-service conditions. Versions prior to QuickTime 7.7.2 are vulnerable on Windows 7, Vista and XP. NOTE: This issue was previously discussed in BID 53547 (Apple QuickTime Prior To 7.7.2 Multiple Arbitrary Code Execution Vulnerabilities), but has been given its own record to better document it.
