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

2017-14633

In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability
exists in the function mapping0_forward() in mapping0.c, which may
lead to DoS when operating on a crafted audio file with
vorbis_analysis().

2017-14632

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.

2017-11333

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.

2018-5146

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.

We recommend that you upgrade your libvorbis packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
