                   Red Hat Security Advisory

Synopsis:          Low: libexif security update
Advisory ID:       RHSA-2005:300-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-300.html
Issue date:        2005-03-21
Updated on:        2005-03-21
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-0664
- - ---------------------------------------------------------------------

1. Summary:

Updated libexif packages that fix a buffer overflow issue are now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

The libexif package contains the EXIF library. Applications use this
library to parse EXIF image files.

A bug was found in the way libexif parses EXIF tags. An attacker could
create a carefully crafted EXIF image file which could cause image viewers
linked against libexif to crash. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2005-0664 to this issue.

Users of libexif should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:

    http://www.redhat.com/docs/manuals/enterprise/
