Bug(s): #439052, #452202, #470734
ID: 201406-28

Synopsis

Multiple vulnerabilities have been found in Libav, allowing
attackers to execute arbitrary code or cause Denial of Service.


Background

Libav is a complete solution to record, convert and stream audio and
video.


Affected Packages

Package: media-video/libav
Vulnerable: < 0.8.7
Unaffected: >= 0.8.7
Architectures: All supported architectures


Description

Multiple vulnerabilities have been discovered in Libav. Please review
the CVE identifiers referenced below for details.


Impact

A remote attacker could entice a user to open a specially crafted media
file in an application linked against Libav, possibly resulting in
execution of arbitrary code with the privileges of the application or a
Denial of Service condition.


Workaround

There is no known workaround at this time.

Resolution

All Libav users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-video/libav-0.8.7"
   
Packages which depend on this library may need to be recompiled. Tools such
