Description

From Red Hat Security Advisory 2018:0649 :

An update for libvorbis is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The libvorbis package contains runtime libraries for use in programs that support Ogg Vorbis, a fully open, non-proprietary, patent- and royalty-free, general-purpose compressed format for audio and music at fixed and variable bitrates.

Security Fix(es) :

  • Mozilla: Vorbis audio processing out of bounds write (MFSA 2018-08) (CVE-2018-5146)
