Vulnerability Note VU#448745
Apple QuickTime PICT heap buffer overflow
OverviewThe Apple QuickTime player contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition.
I. DescriptionPICT is a graphics file format that was used by Apple Macintosh systems prior to OS X as their standard metafile format. OS X systems can open and display PICT files.
Apple QuickTime contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code with the privileges of the user running QuickTime. By convincing a user to open a specially crafted PICT file with QuickTime, an attacker can trigger the overflow.
Apple iTunes includes the QuickTime player.
Note that this vulnerability may be present in QuickTime versions prior to 7.1.5 running on Mac OS X and Microsoft Windows 2000, XP and Vista.
II. ImpactA remote, unauthenticated attacker can execute arbitrary code or create a denial-of-service condition. The crafted QuickTime PICT 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.
III. SolutionUpdate
Apple has released QuickTime 7.5 to address this issue.
