Description Oleg Golberg 2005-08-26 10:32:38 UTC

Quoting the webpage of Sven Tantau who found the vulnerability:

"Affected Version: 1.0_pre7 (tested), 1.0_pre6-r4 (tested),
1.0pre6-3.3.5-20050130 (confirmed)
<...>
For high values of the 2 bytes strf parameter in the audio header of a
video file, it is possible to overflow sh_audio->a_buffer, overwrite the
instruction pointer and execute arbitrary code 
<...>
MPlayer developers patched the problem:
http://www1.mplayerhq.hu/cgi-bin/cvsweb.cgi/main/libmpcodecs/ad_pcm.c.diff?r1=1.18&r2=1.19"

The patch applies cleanly to media-video/mplayer-1.0-pre7

Reproducible: Always
