Mandriva Linux Security Advisory MDKSA-2006:174
http://www.mandriva.com/security/
_______________________________________________________________________

Package : gstreamer-ffmpeg
Date : September 28, 2006
Affected: 2006.0, 2007.0
_______________________________________________________________________

Problem Description:

Gstreamer-ffmpeg uses an embedded copy of ffmpeg and as such has been
updated to address the following issue: Multiple buffer overflows in
libavcodec in ffmpeg before 0.4.9_p20060530 allow remote attackers to
cause a denial of service or possibly execute arbitrary code via
multiple unspecified vectors in (1) dtsdec.c, (2) vorbis.c, (3) rm.c,
(4)sierravmd.c, (5) smacker.c, (6) tta.c, (7) 4xm.c, (8) alac.c, (9)
cook.c, (10)shorten.c, (11) smacker.c, (12) snow.c, and (13) tta.c.
NOTE: it is likely that this is a different vulnerability than
CVE-2005-4048 and CVE-2006-2802.

Updated packages have been patched to correct this issue.
