Notes
[squeeze] - liblivemedia <not-affected> (vuln. code introduced in 2011.08.13)
[squeeze] - vlc <not-affected> (not built against vuln. liblivemedia)
[squeeze] - mplayer <no-dsa> (Minor issue)
- mplayer2 <not-affected> (b-d's on liblivemedia but doesn't actually build the support for it)
vlc fixed by binNMU 2.1.2-2+b1, but since binNMUs are not visible to the security tracker, the subsequent sid upload is tracked
for wheezy the version present at release of DSA 3156 is used (2.0.3-5+deb7u2), although strictly speaking it's 2.0.3-5+deb7u2+b1
