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 >= 0.4.9_p20090201 2 gst-plugins-ffmpeg < 0.10.5 >= 0.10.5 3 mplayer < 1.0_rc2_p28450 >= 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 >=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" References ========== [ 1 ] CVE-2008-3162 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3162 [ 2 ] CVE-2008-4866 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4866 [ 3 ] CVE-2008-4867 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4867 [ 4 ] CVE-2008-4868 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4868 [ 5 ] CVE-2008-4869 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4869 [ 6 ] CVE-2009-0385 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0385 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200903-33.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
