VLC: User-assisted execution of arbitrary code — GLSA 200804-25

Multiple vulnerabilities were found in VLC, allowing for the execution of arbitrary code.

Affected Packages

media-video/vlc on all architectures
Affected versions < 0.8.6f
Unaffected versions >= 0.8.6f


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


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).


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.


There is no known workaround at this time.


All VLC users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6f"
