GLSA-200806-09 : libvorbis: Multiple vulnerabilities

High Nessus Plugin ID 33245


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200806-09 (libvorbis: Multiple vulnerabilities)

Will Drewry of the Google Security Team reported multiple vulnerabilities in libvorbis:
A zero value for 'codebook.dim' is not properly handled, leading to a crash, infinite loop or triggering an integer overflow (CVE-2008-1419).
An integer overflow in 'residue partition value' evaluation might lead to a heap-based buffer overflow (CVE-2008-1420).
An integer overflow in a certain 'quantvals' and 'quantlist' calculation might lead to a heap-based buffer overflow (CVE-2008-1423).
Impact :

A remote attacker could exploit these vulnerabilities by enticing a user to open a specially crafted Ogg Vorbis file or network stream with an application using libvorbis. This might lead to the execution of arbitrary code with the privileges of the user playing the file or a Denial of Service by a crash or CPU consumption.
Workaround :

There is no known workaround at this time.


All libvorbis users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libvorbis-1.2.1_rc1'
