Severity: normal
Exploitable: remote
Date: April 23, 2008
Bug(s): #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: media-video/vlc
Vulnerable: < 0.8.6f
Unaffected: >= 0.8.6f
Architectures: 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:
