Debian DLA-780-1 : libav security update

medium Nessus Plugin ID 96458

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities have been found in libav :

CVE-2016-7424

The put_no_rnd_pixels8_xy2_mmx function in x86/rnd_template.c in libav 11.7 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted MP3 file.

(No CVE assigned)

The h264 codec is vulnerable to various crashes with invalid-free, corrupted double-linked list or out-of-bounds read.

For Debian 7 'Wheezy', these problems have been fixed in version 6:0.8.19-0+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.
