Package : mencoder
Type    : denial of service
Remote  : Yes
Link    : https://wiki.archlinux.org/index.php/CVE

Summary
=======

The package mencoder before version 37857-1 is vulnerable to denial of
service.

Resolution
==========

Upgrade to 37857-1.

# pacman -Syu "mencoder>=37857-1"

The problem has been fixed upstream in version 37857.

Description
===========

A vulnerability has been discovered that is leading to a crash when
playing a fuzzed gif file. The gif demuxes assumed in many places that
width*height is <= INT_MAX, however this was not always true and was
leading to an integer overflow.

Impact
======

A remote attacker is able to use a specially crafted gid file that, when
processed, is resulting in an application crash leading to denial of
service.
