Gentoo Linux Security Advisory

Title: xine-lib, FFmpeg: Heap-based buffer overflow (GLSA 200601-06)
Severity: normal
Exploitable: remote
Date: January 10, 2006
Bug(s): #115849, #116181
ID: 200601-06

Synopsis


xine-lib and FFmpeg are vulnerable to a buffer overflow that may be
exploited by attackers to execute arbitrary code.


Background


xine is a GPL high-performance, portable and reusable multimedia
playback engine. xine-lib is xine's core engine. FFmpeg is a very fast
video and audio converter and is used in xine-lib.


Affected Packages

Package: media-libs/xine-lib
Vulnerable: < 1.1.1-r3
Unaffected: >= 1.1.1-r3
Architectures: All supported architectures

Package: media-video/ffmpeg
Vulnerable: < 0.4.9_p20051216
Unaffected: >= 0.4.9_p20051216
Architectures: All supported architectures


Description


Simon Kilvington has reported a vulnerability in FFmpeg
libavcodec. The flaw is due to a buffer overflow error in the
"avcodec_default_get_buffer()" function. This function doesn't properly
handle specially crafted PNG files as a result of a heap overflow.


Impact


A remote attacker could entice a user to run an FFmpeg based
application on a maliciously crafted PNG file, resulting in the
execution of arbitrary code with the permissions of the user running
the application.


Workaround


There is no known workaround at this time.


Resolution


All xine-lib users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.1-r3"

All FFmpeg users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/ffmpeg-0.4.9_p20051216"
