Titel:	Mandriva Security Advisory MDVSA-2011:059 (ffmpeg)
Zusammenfassung:	NOSUMMARY
Beschreibung:	Description: The remote host is missing an update to ffmpeg announced via advisory MDVSA-2011:059. Multiple vulnerabilities has been identified and fixed in ffmpeg: Multiple integer underflows in FFmpeg 0.5 allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted file that (1) bypasses a validation check in vorbis_dec.c and triggers a wraparound of the stack pointer, or (2) access a pointer from out-of-bounds memory in mov.c, related to an elst tag that appears before a tag that creates a stream. (CVE-2009-4634) FFmpeg 0.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted MOV container with improperly ordered tags that cause (1) mov.c and (2) utils.c to use inconsistent codec types and identifiers, which causes the mp3 decoder to process a pointer for a video structure, leading to a stack-based buffer overflow. (CVE-2009-4635) The av_rescale_rnd function in the AVI demuxer in FFmpeg 0.5 allows remote attackers to cause a denial of service (crash) via a crafted AVI file that triggers a divide-by-zero error. (CVE-2009-4639) And several additional vulnerabilites originally discovered by Google Chrome developers were also fixed with this advisory. The updated packages have been patched to correct these issues. Affected: Corporate 4.0 Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you. http://www.securityspace.com/smysecure/catid.html?in=MDVSA-2011:059 Risk factor : Critical CVSS Score: 10.0
