Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200710-03
(libvorbis: Multiple vulnerabilities)

David Thiel of iSEC Partners discovered a heap-based buffer overflow in
the _01inverse() function in res0.c and a boundary checking error in
the vorbis_info_clear() function in info.c (CVE-2007-3106 and
CVE-2007-4029). libvorbis is also prone to several Denial of Service
vulnerabilities in form of infinite loops and invalid memory access
with unknown impact (CVE-2007-4065 and CVE-2007-4066).

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 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.

Solution :

All libvorbis users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/libvorbis-1.2.0'

Risk factor :

Medium / CVSS Base Score : 6.8
