Synopsis

Multiple vulnerabilities in FFmpeg may lead to the remote execution of arbitrary code or a Denial of Service.

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-video/ffmpeg	< 0.4.9_p20090201	>= 0.4.9_p20090201	All supported architectures
media-plugins/gst-plugins-ffmpeg	< 0.10.5	>= 0.10.5	All supported architectures
media-video/mplayer	< 1.0_rc2_p28450	>= 1.0_rc2_p28450	All supported architectures

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.

Workaround

There is no known workaround at this time.

Resolution

All FFmpeg users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/ffmpeg-0.4.9_p20090201"

All gst-plugins-ffmpeg users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-plugins/gst-plugins-ffmpeg-0.10.5"

All Mplayer users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_rc2_p28450"
