FFmpeg: Buffer overflows

Background

FFmpeg is a very fast video and audio converter.

Description

FFmpeg contains buffer overflows in the AVI processing code.

Impact

An attacker could trigger the buffer overflows by enticing a user to load a specially crafted AVI file in an application using the FFmpeg library. This might result in the execution of arbitrary code in the context of the running application.

Workaround

There is no known workaround at this time.

Resolution

All FFmpeg users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-video/ffmpeg-0.4.9_p20060530"
