Red Hat Security Advisory

Synopsis: Moderate: libexif security update
Advisory ID: RHSA-2007:1165-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-1165.html
Issue date: 2007-12-19
Updated on: 2007-12-19
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-6351 CVE-2007-6352
- ---------------------------------------------------------------------

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

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.
