Synopsis
Multiple vulnerabilities in FFmpeg may lead to the remote execution of
arbitrary code or a Denial of Service.
2.
Impact Information
Background
FFmpeg is a complete solution to record, convert and stream audio and
video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which
includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia
player which also includes a vulnerable copy of the code.
Description
Multiple vulnerabilities were found in FFmpeg:
- astrange
reported a stack-based buffer overflow in the str_read_packet() in
libavformat/psxstr.c when processing .str files (CVE-2008-3162).
- Multiple buffer overflows in libavformat/utils.c
(CVE-2008-4866).
- A buffer overflow in libavcodec/dca.c
(CVE-2008-4867).
- An unspecified vulnerability in the
avcodec_close() function in libavcodec/utils.c (CVE-2008-4868).
- Unspecified memory leaks (CVE-2008-4869).
- Tobias Klein
repoerted a NULL pointer dereference due to an integer signedness error
in the fourxm_read_header() function in libavformat/4xm.c
(CVE-2009-0385).
Impact
A remote attacker could entice a user to open a specially crafted media
file, possibly leading to the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.

Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All FFmpeg users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/ffmpeg-0.4.9_p20090201"
|
All gst-plugins-ffmpeg users should upgrade to the latest version:
Code Listing 3.2: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-ffmpeg-0.10.5"
|
All Mplayer users should upgrade to the latest version:
Code Listing 3.3: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_rc2_p28450"
|
