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 ------------------------------------------------------------------- 1 ffmpeg < 0.4.9_p20090201 >=3D 0.4.9_p20090201 2 gst-plugins-ffmpeg < 0.10.5 >=3D 0.10.5 3 mplayer < 1.0_rc2_p28450 >=3D 1.0_rc2_p28450 ------------------------------------------------------------------- 3 affected packages on all of their 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 >=3Dmedia-video/ffmpeg-0.4.9_p20090201= "
All gst-plugins-ffmpeg users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose >=3Dmedia-plugins/gst-plugins-ffmpeg-0.10.5"
All Mplayer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose >=3Dmedia-video/mplayer-1.0_rc2_p28450= "
