New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
