Mandrake Linux Security Advisory : xmovie (MDKSA-2005:229)
High Nessus Plugin ID 20460
SynopsisThe remote Mandrake Linux host is missing a security update.
DescriptionSimon Kilvington discovered a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
The vulnerability is caused due to a boundary error in the 'avcodec_default_get_buffer()' function of 'utils.c' in libavcodec.
This can be exploited to cause a heap-based buffer overflow when a specially crafted 1x1 '.png' file containing a palette is read.
Xmovie is built with a private copy of ffmpeg containing this same code.
The updated packages have been patched to prevent this problem.
SolutionUpdate the affected xmovie package.
