Background
Mplayer is a popular media player that supports various audio and video formats. It is widely used for playing multimedia files on Debian 7 Wheezy. However, a vulnerability has been discovered in mplayer that can lead to crashes when playing certain gif files. The issue arises from assumptions made by the gif demuxer regarding the size of the picture, which can result in an integer overflow. This vulnerability could potentially be exploited by an attacker to execute arbitrary code or cause a denial of service.
Vulnerability Detail
The vulnerability in mplayer arises from the gif demuxer's assumption that the product of width and height of a picture is always less than or equal to INT_MAX. However, this assumption may not hold true in all cases, leading to an integer overflow. To address this issue, the picture size is now validated to ensure it does not exceed the maximum allowed value. This fix prevents crashes and potential exploitation of the vulnerability.
