 Mandriva Linux Security Advisory                         MDVSA-2012:023
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : libvpx
 Date    : February 27, 2012
 Affected: 2010.1, 2011.
 _______________________________________________________________________

 Problem Description:

 A vulnerability has been found and corrected in libvpx:
 
 VP8 Codec SDK (libvpx) before 1.0.0 Duclair allows remote attackers
 to cause a denial of service (application crash) via (1) unspecified
 corrupt input or (2) by starting decoding from a P-frame, which
 triggers an out-of-bounds read, related to the clamping of motion
 vectors in SPLITMV blocks (CVE-2012-0823).
 
 The updated packages have been patched to correct this issue.
