"Two issues have been found in libvorbis, a decoder library for Vorbis
General Audio Compression Codec.

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().

2017-11333

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.

For Debian 8 'Jessie', these problems have been fixed in version
1.3.4-2+deb8u3.

We recommend that you upgrade your libvorbis packages.
