Debian DLA-644-1 : libav security update

Medium Nessus Plugin ID 93847

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities have been found in libav :

CVE-2015-1872

The ff_mjpeg_decode_sof function in libavcodec/mjpegdec.c in Libav before 0.8.18 does not validate the number of components in a JPEG-LS Start Of Frame segment, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Motion JPEG data.

CVE-2015-5479

The ff_h263_decode_mba function in libavcodec/ituh263dec.c in Libav before 11.5 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a file with crafted dimensions.

CVE-2016-7393

The aac_sync function in libavcodec/aac_parser.c in Libav before 11.5 is vulnerable to a stack-based buffer overflow.

For Debian 7 'Wheezy', these problems have been fixed in version 6:0.8.18-0+deb7u1.

We recommend that you upgrade your libav packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
