Name        : libvorbis
Product     : Fedora 7
Version     : 1.1.2
Release     : 4.fc7
URL         : http://www.xiph.org/
Summary     : The Vorbis General Audio Compression Codec.
Description :
Ogg Vorbis is a fully open, non-proprietary, patent-and royalty-free,
general-purpose compressed audio format for audio and music at fixed
and variable bitrates from 16 to 128 kbps/channel.

The libvorbis package contains runtime libraries for use in programs
that support Ogg Voribs.

Update Information:

Will Drewry of the Google Security Team reported several flaws in the way
libvorbis processed audio data. An attacker could create a carefully  crafted
OGG audio file in such a way that it could cause an application  linked with
libvorbis to crash, or execute arbitrary code when it was  opened.
(CVE-2008-1419, CVE-2008-1420, CVE-2008-1423)    Moreover, additional OGG file
sanity-checks have been added to prevent  possible exploitation of similar
issues in the future.
