Serious vulnerabilities were found in the libvorbis library, commonly used to encode and decode audio in OGG containers.

Xiph.Org libvorbis 1.3.5 allows Remote Code Execution upon freeing uninitialized memory in the function vorbis_analysis_headerout() in info.c when vi->channels<=0, a similar issue to Mozilla bug 550184.
The vorbis_analysis_wrote function in lib/block.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a denial of service (OOM) via a crafted wav file.
out-of-bounds memory write in the codeboook parsing code of the Libvorbis multimedia library could result in the execution of arbitrary code.
For Debian 7
Wheezy, these problems have been fixed in version 1.3.2-1.3+deb7u1.
