Package        : libvorbis
Version        : 1.3.2-1.3+deb7u1
CVE ID         : CVE-2017-11333 CVE-2017-14632 CVE-2017-14633 CVE-2018-5146

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.
