Synopsis

========

 

Multiple vulnerabilities in VLC may lead to the remote execution of

arbitrary code.

 

Background

==========

 

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

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-video/vlc < 0.9.8a >= 0.9.8a

 

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.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All VLC users should upgrade to the latest version:

 

# emerge --sync

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