[Vorbis] libvorbis 1.3.6 - critical security update

[Jean-Marc Valin]

Many thanks to Thomas for handling this security issue quickly. For
those who need just the most critical CVE (though the other CVEs should
be patched as well), the fixes are:

Vorbis:
https://git.xiph.org/?p=vorbis.git;a=commitdiff;h=667ceb4a

Tremor:
https://git.xiph.org/?p=tremor.git;a=commitdiff;h=562307a4

Cheers,

	Jean-Marc
