Severity:	normal
Title:	VLC: User-assisted execution of arbitrary code
Date:	04/23/2008
Bugs:	#214277, #214627
ID:	200804-25

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	Architecture(s)
media-video/vlc	< 0.8.6f	>= 0.8.6f	All supported architectures

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"
