Red Hat Security Advisory Synopsis: New mutt packages available to fix security problem Advisory ID: RHSA-2002:003-10 Issue date: 2002-01-01 Updated on: 2002-01-07 Product: Red Hat Linux Keywords: mutt rfc822 overflow address parser Cross references: Obsoletes: --------------------------------------------------------------------- 1. Topic: New mutt packages that fix an overflow in mutt's address parsing code are available. It is recommended that all mutt users update to the fixed packages. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386, sparc Red Hat Linux 7.0J - i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 3. Problem description: An overflow exists in mutt's RFC822 address parser. A remote attacker could send a carefully crafted email message which when read by mutt would be able to overwrite arbitrary bytes in memory. The updated mutt-1.2.5.1 release fixes the problem. Thanks go to Joost Pol for discovering the bug and the Mutt team for the fixed release. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0001 to 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. Pleasenote 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.
