"Serious vulnerabilities were found in the libvorbis library, commonly

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
