Synopsis

Two vulnerabilities in VLC may lead to the remote execution of arbitrary code.

2. Impact Information

Background

VLC is a cross-platform media player and streaming server.

Description

g_ reported the following vulnerabilities:

An integer overflow leading to a heap-based buffer overflow in the Open() function in modules/demux/tta.c (CVE-2008-3732).
A signedness error leading to a stack-based buffer overflow in the mms_ReceiveCommand() function in modules/access/mms/mmstu.c (CVE-2008-3794).

Impact

A remote attacker could entice a user to open a specially crafted file, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All VLC users should upgrade to the latest version:
