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. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/n-071.shtml ORIGINAL BULLETIN: https://rhn.redhat.com/errata/RHSA-2003-128.html ______________________________________________________________________________ [***** Start Red Hat Security Advisory RHSA-2003:128-07 *****] 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 CVEs (cve.mitre.org): CAN-2003-0165 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.

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.
