Background ========== VLC is a cross-platform media player and streaming server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/vlc < 0.8.6f >= 0.8.6f Description =========== Multiple vulnerabilities were found in VLC: * Luigi Auriemma discovered that the stack-based buffer overflow when reading subtitles, which has been reported as CVE-2007-6681 in GLSA 200803-13, was not properly fixed (CVE-2008-1881). * Alin Rad Pop of Secunia reported an array indexing vulnerability in the sdpplin_parse() function when processing streams from RTSP servers in Xine code, which is also used in VLC (CVE-2008-0073). * Drew Yao and Nico Golde reported an integer overflow in the MP4_ReadBox_rdrf() function in the file libmp4.c leading to a heap-based buffer overflow when reading MP4 files (CVE-2008-1489). * Drew Yao also reported integer overflows in the MP4 demuxer, the Real demuxer and in the Cinepak codec, which might lead to buffer overflows (CVE-2008-1768). * Drew Yao finally discovered and a boundary error in Cinepak, which might lead to memory corruption (CVE-2008-1769). Impact ====== A remote attacker could entice a user to open a specially crafted media file or stream, possibly resulting in the remote execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All VLC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6f" References ========== [ 1 ] CVE-2007-6681 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6681 [ 2 ] CVE-2008-0073 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0073 [ 3 ] CVE-2008-1489 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1489 [ 4 ] CVE-2008-1768 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1768 [ 5 ] CVE-2008-1769 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1769 [ 6 ] CVE-2008-1881 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1881 [ 7 ] GLSA 200803-13 http://www.gentoo.org/security/en/glsa/glsa-200803-13.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-25.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.
