Yellow Dog Linux Security Announcement -------------------------------------- Package: mutt Issue Date: January 27, 2002 Priority: high Advisory ID: YDU-20020127-4 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. Problem: 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 (from Red Hat advisory) 3. Solution: a) Updating via yup... We suggest that you use the Yellow Dog Update Program (yup) to keep your system up-to-date.
