A vulnerability exists in how Apple OS X handles PICT images. If successfully exploited, this vulnerability may allow a remote attacker to execute arbitrary code, or create a denial-of-service condition.
Certain applications invoke an unsupported QuickDraw operation to display PICT images. By carefully crafting a corrupt PICT image, an attacker can trigger memory corruption in these applications, which may lead to an application crash or arbitrary code execution. This update addresses the issue by preventing the unsupported operation.
A remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user who opened the malicious file.
Apple has released an update that addresses this issue.
Do not open unknown files with privileged accounts
Opening unknown files using user accounts with limited privileges may mitigate the affects of this vulnerability. See the Home Network Security document for more details.
