(Red Hat Issues Fix) libexif Buffer Overflow in Processing EXIF Headers May Let Remote Users Crash the Application
SecurityTracker Alert ID:  1013495
SecurityTracker URL:  http://securitytracker.com/id/1013495
CVE Reference:   CVE-2005-0664   (Links to External Site)
Updated:  Jun 13 2007
Original Entry Date:  Mar 21 2005
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.6.9 and prior versions
Description:   A buffer overflow vulnerability was reported in libexif. A remote user may be able to cause a target user's application to crash or execute arbitrary code.

The exif library does not properly validate user-supplied input in several places. A remote user can create a specially crafted JPEG image with invalid EXIF header data. When the image is loaded by the target user's application that uses libexif, the application may crash or potentially execute arbitrary code.

The flaw resides in 'exif-data.c'.

Sylvain Defresne discovered this vulnerability.

Impact:   A remote user can create an image file that, when loaded by the target user's application, will cause the application to crash or potentially execute arbitrary code.
Solution:   Red Hat has released a fix.

Hash: SHA1

- ---------------------------------------------------------------------
                   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

following Web page for the System Administration or Customization
guide specific to your system:
