Red Hat Linux 9 RHSA-2004:051-01 Critical: Mutt Remote Code Execution

New mutt packages that fix a remotely-triggerable crash in the menu drawing code are now available.. - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated mutt packages fix remotely-triggerable crash Advisory ID: RHSA-2004:051-01 Issue date: 2004-02-11 Updated on: 2004-02-11 Product: Red Hat Linux Keywords: mutt menu crash Cross references: Obsoletes: CVE Names: CAN-2004-0078 - --------------------------------------------------------------------- 1. Topic: New mutt packages that fix a remotely-triggerable crash in the menu drawing code are now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: Mutt is a text-mode mail user agent. A bug was found in the index menu code in versions of mutt. A remote attacker could send a carefully crafted mail message that can cause mutt to segfault and possibly execute arbitrary code as the victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0078 to this issue. It is recommended that all mutt users upgrade to these updated packages, which contain a backported security patch and are not vulnerable to this issue. Red Hat would like to thank Niels Heinen for reporting 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 RedHat 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. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://access.redhat.com 5.
