Description

Various security issues were discovered in faad2, a fast audio decoder, that would allow remote attackers to cause a denial of service (application crash due to memory failures or large CPU consumption) via a crafted mp4 file.

For Debian 7

For Debian 7 'Wheezy', these problems have been fixed in version
2.7-8+deb7u1.

We recommend that you upgrade your faad2 packages.

introducing additional issues."
