Topic: New groff packages have been made available that fix an overflow in groff. If the printing system running this is a security issue, it is recommended to update to the new, fixed packages. 2. Relevant releases/architectures: Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 3. Problem description: Groff is a document formatting system. The groff preprocessor contains an exploitable buffer overflow. If groff can be invoked within the LPRng printing system, an attacker can gain rights as the "lp" user. Remote exploitation may be possible if lpd is running and is accessible remotely, and the attacker knows the name of the printer and spoolfile. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0003 to this issue. Thanks to zen-parse for bringing this bug to our attention. 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.
