Title: Apple QuickTime Color Table ID Heap Overflow Vulnerability
Severity: HIGH
Description:
QuickTime Player is the media player distributed by Apple for QuickTime and other media files.
QuickTime is prone to a heap-overflow vulnerability because it fails to perform adequate bounds checking on user-supplied data.
The problem occurs when QuickTime handles specially crafted video media atoms. Specifically, when QuickTime encounters a 0 value in the 'Color table ID' field of the Video Sample Description, it expects a color table to follow the description. This results in a byte-swap process being run on the section of memory following the description where a color table is expected to be present.
An attacker can exploit this vulnerability to corrupt heap memory and execute arbitrary code in the context of the user running the application. Failed exploit attempts will likely cause denial-of-service conditions.
QuickTime 7.1.3 is vulnerable; other versions may also be affected.
This issue was previously discussed in BID 22827 (Apple QuickTime Multiple Unspecified Code Execution Vulnerabilities), but has been assigned its own record because of new information.
Affected Products:
- Apple QuickTime Player 7.1.3
