Apple QuickTime contains a stack buffer overflow vulnerability. If exploited, this vulnerability may allow an attacker to execute code.


Apple QuickTime is a media player that includes a browser plugin. QuickTime can display PICT images.

From Apple Article ID: 306896 "About the security content of QuickTime 7.3":
A stack buffer overflow exists in PICT image processing. By enticing a user to open a maliciously crafted image, an attacker may cause an unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of PICT files. Credit to Ruben Santamarta of working with TippingPoint and the Zero Day Initiative for reporting this issue.
To exploit this vulnerability, an attacker would have to convince a user to open a specially crafted PICT image, which could be hosted on a web page.
