An updated metamail package that fixes a buffer overflow vulnerability for CentOS Linux 2.1 is now available. This update has been rated as having important security impact by the Red Hat Security Response Team.
Metamail is a system for handling multimedia mail. A buffer overflow bug was found in the way Metamail processes certain mail messages. An attacker could create a carefully-crafted message such that when it is opened by a victim and parsed through Metamail, it runs arbitrary code as the victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-0709 to this issue. Users of Metamail should upgrade to this updated package, which contains a backported patch that is not vulnerable to this issue.
