Discussion

FFmpeg and Libav 'libavcodec/wmalosslessdec.c' Memory Corruption Vulnerability

FFmpeg and Libav are prone to a memory-corruption vulnerability because it fails to adequately bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

Attackers can leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.

NOTE: These issues were previously discussed in BID 65504 (FFmpeg Multiple Denial of Service Vulnerabilities) but have been given their own record to better document them.
