Description

From Red Hat Security Advisory 2007:0501 :

Updated libexif packages that fix an integer overflow flaw are now available for Red Hat Enterprise Linux 4 and 5.

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

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

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-2007-4168)

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