Details

XFOCUS Security Team discovered that the AVI decoder used in xine-lib did not
correctly validate certain headers. By tricking a user into playing an AVI
with malicious headers, an attacker could execute arbitrary code with the
target user's privileges. (CVE-2006-4799)

Multiple integer overflows were discovered in ffmpeg and tools that contain a
copy of ffmpeg (like xine-lib and kino), for several types of video formats.
By tricking a user into running a video player that uses ffmpeg on a stream
with malicious content, an attacker could execute arbitrary code with the
target user's privileges. (CVE-2006-4800)
