ID de Prueba:	1.3.6.1.4.1.25623.1.0.55986
Categoría:	Mandrake Local Security Checks
Título:	Mandrake Security Advisory MDKSA-2005:232 (gstreamer-ffmpeg)
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing an update to gstreamer-ffmpeg announced via advisory MDKSA-2005:232. Simon Kilvington discovered a vulnerability in FFmpeg libavcodec, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system. The vulnerability is caused due to a boundary error in the avcodec_default_get_buffer() function of utils.c in libavcodec. This can be exploited to cause a heap-based buffer overflow when a specially-crafted 1x1 .png file containing a palette is read. Gstreamer-ffmpeg is built with a private copy of ffmpeg containing this same code. The updated packages have been patched to prevent this problem. Affected: 2006.0 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=MDKSA-2005:232 Risk factor : High CVSS Score: 7.5
