Synopsis

========

 

Multiple vulnerabilities were found in VLC, allowing for the execution

of arbitrary code.

 

Background

==========

 

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

 

Affected packages

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

 

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

Package / Vulnerable / Unaffected

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

1 media-video/vlc < 0.8.6f >= 0.8.6f

 

Description

===========

 

Multiple vulnerabilities were found in VLC:

 

* Luigi Auriemma discovered that the stack-based buffer overflow when

reading subtitles, which has been reported as CVE-2007-6681 in GLSA

200803-13, was not properly fixed (CVE-2008-1881).

 

* Alin Rad Pop of Secunia reported an array indexing vulnerability in

the sdpplin_parse() function when processing streams from RTSP

servers in Xine code, which is also used in VLC (CVE-2008-0073).

 

* Drew Yao and Nico Golde reported an integer overflow in the

MP4_ReadBox_rdrf() function in the file libmp4.c leading to a

heap-based buffer overflow when reading MP4 files (CVE-2008-1489).

 

* Drew Yao also reported integer overflows in the MP4 demuxer, the

Real demuxer and in the Cinepak codec, which might lead to buffer

overflows (CVE-2008-1768).

 

* Drew Yao finally discovered and a boundary error in Cinepak, which

might lead to memory corruption (CVE-2008-1769).

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted media

file or stream, possibly resulting in the remote execution of arbitrary

code.

 

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-0.8.6f"
