CVE-2007-3901


Description:
Two vulnerabilities have been reported in Microsoft DirectX, which can be exploited by malicious people to compromise a user's system.

1) A boundary error in quartz.dll when parsing SAMI (Synchronized Accessible Media Interchange) files can be exploited to cause a stack-based buffer overflow when opening a specially crafted file.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in DirectX 7.0 and 8.1. Later versions are not affected.

2) An error within the DirectShow technology when parsing AVI and WAV files can be exploited to execute arbitrary code on a user's system when e.g. visiting a malicious website.

The vulnerability has been reported in DirectX 7.0 through 10.0.

Solution:
Apply patches.
