Advisory:	RHSA-2007:0501-4
Type:	Security Advisory
Severity:	Moderate
Issued on:	2007-06-14
Last updated on:	2007-06-14
Affected Products:	RHEL Desktop Workstation (v. 5 client) Red Hat Desktop (v. 4) Red Hat Enterprise Linux (v. 5 server) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux Desktop (v. 5 client) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 4)
OVAL:	N/A
CVEs (cve.mitre.org):	CVE-2006-4168

Details

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.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
