______________________________________________________________________________
PROBLEM:       A format string vulnerability exists in Eye of GNOME (EOG). 
PLATFORM:      * Red Hat Linux 8.0 
               * Red Hat Linux 9 
DAMAGE:        A carefully crafted filename passed to a program could lead to 
               the execution of arbitrary code. 
SOLUTION:      Apply updated packages per Red Hat's security advisory. 
______________________________________________________________________________
VULNERABILITY  The risk is MEDIUM. EOG is a widely used in Red Hat Linux 
ASSESSMENT:    packages for displaying images. The vulnerability allows an 
               attacker to execute arbitrary code through format string 
               specifiers in a command line argument for the file to display.

Updated Eye of GNOME packages fix vulnerability

Advisory: RHSA-2003:128-07 
Last updated on: 2003-04-03 
Affected Products: Red Hat Linux 8.0
Red Hat Linux 9

Security Advisory 

Details:

Updated eog packages that fix a security vulnerability are now available.

Eye of GNOME (EOG) is a component for the GNOME desktop used by various Red
Hat Linux packages for displaying images.

A vulnerability was found in EOG version 2.2.0 and earlier. A carefully
crafted filename passed to the program could lead to the execution of
arbitrary code. An attacker could exploit this because various packages
(Mutt, for example) make use of EOG for image viewing.

All users are advised to upgrade to these erratum packages which contain a
backported patch correcting this issue.

Solution

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

You can verify each package and see who signed it with the following command:

rpm --checksig -v filename 

If you only wish to verify that each package has not been corrupted or tampered 
with, examine only the md5sum with the following command:

md5sum filename
