Topic: Updated Xpdf packages are available that fix a vulnerability where a malicious PDF document could run arbitrary code. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: Xpdf is an X Window System based viewer for Portable Document Format (PDF) files. Martyn Gilmore discovered a flaw in various PDF viewers and readers. An attacker can embed malicious external-type hyperlinks that if activated or followed by a victim can execute arbitrary shell commands. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0434 to this issue. All users of Xpdf are advised to upgrade to these errata packages, which contain a patch to correct this issue. 4. 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. 5.
