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"
