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 ‘Wheezy’, these problems have been fixed in version 2.7-8+deb7u1.
We recommend that you upgrade your faad2 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.
