Apple QuickTime PictureViewer contains a buffer overflow that may allow a remote attacker to execute arbitrary code on a vulnerable system.
Apple's QuickTime Player is multimedia software that allows users to view local and remote audio/video content. PictureViewer is a QuickTime component used to view still images. A lack of input validation in Apple QuickTime PictureViewer may allow a buffer overflow to occur. The overflow occurs because PictureViewer does not properly validate the size of compressed PICT data. When PictureViewer decompresses the PICT data, that data is copied to a buffer of insufficient size resulting in a buffer overflow.
For more information, please see Apple Security Update for QuickTime.
A remote attacker may be able to execute arbitrary code if they can persuade a user to access a specially crafted compressed PICT file.
Do not access PICT files from untrusted sources
