RHEL 5 : libexif (RHSA-2007:1165)

Synopsis :

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

Description :

Updated libexif packages that fix several security issues are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The libexif packages contain the Exif library. Exif is an image file
format specification that enables metadata tags to be added to
existing JPEG, TIFF and RIFF files. The Exif library makes it possible
to parse an Exif file and read this metadata.

An infinite recursion flaw was found in the way libexif parses Exif
image tags. If a victim opens a carefully crafted Exif image file, it
could cause the application linked against libexif to crash.
(CVE-2007-6351)

An integer overflow flaw was found in the way libexif parses Exif
image tags. If a victim opens a carefully crafted Exif image file, it
could cause the application linked against libexif to execute
arbitrary code, or crash. (CVE-2007-6352)

Users of libexif are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.
