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.
