This signature detects the stack overflow vulnerability in the Apple Quicktime versions that are prior to 7.7.2.
Apple QuickTime is a media player that supports multiple file formats.
Apple QuickTime is prone to multiple stack-based buffer-overflow vulnerabilities when parsing the XML elements within a TeXML files. Specifically, these issues occur because the 'QuickTime3GPP.qtx' code fails to properly validate the length of the 'transform', 'sampleData', 'Style', and 'Karaoke' elements before copying it into a fixed-length buffer.
Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts may 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.
- Versions prior to QuickTime 7.7.2 are vulnerable on Windows 7, Vista and XP.
