Synopsis

Multiple 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

Tobias Klein reported the following vulnerabilities:

A stack-based buffer overflow when processing CUE image files in modules/access/vcd/cdrom.c (CVE-2008-5032).
A stack-based buffer overflow when processing RealText (.rt) subtitle files in the ParseRealText() function in modules/demux/subtitle.c (CVE-2008-5036).
An integer overflow when processing RealMedia (.rm) files in the ReadRealIndex() function in real.c in the Real demuxer plugin, leading to a heap-based buffer overflow (CVE-2008-5276).

Impact

A remote attacker could entice a user to open a specially crafted CUE image file, RealMedia file or RealText subtitle file, possibly resulting in the 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:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.9.8a"
