RHEL 5 / 6 : libtiff (RHSA-2012:0468)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated libtiff packages that fix two security issues are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.

Two integer overflow flaws, leading to heap-based buffer overflows,
were found in the way libtiff attempted to allocate space for a tile
in a TIFF image file. An attacker could use these flaws to create a
specially-crafted TIFF file that, when opened, would cause an
application linked against libtiff to crash or, possibly, execute
arbitrary code. (CVE-2012-1173)

All libtiff users should upgrade to these updated packages, which
contain a backported patch to resolve these issues. All running
applications linked against libtiff must be restarted for this update
to take effect.
