Apple QuickDraw contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition.
PICT is a graphics file format that was used by Apple Macintosh systems prior to Mac OS X as their standard metafile format. OS X systems can open and display PICT files. Apple QuickDraw is a two dimensional graphics library that has been deprecated in Mac OS version 10.4.
Apple QuickDraw contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code. By convincing a user to open a specially crafted PICT file with an application that uses the QuickDraw libraries, an attacker can trigger the overflow.
A remote unauthenticated attacker may be able to execute arbitrary code or create a denial-of-service condition. The specially crafted PICT file used to exploit this vulnerability 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 process the file with a vulnerable application.
