3. Problem description:

Elm is a terminal mode email client.

A buffer overflow flaw in Elm was discovered that was triggered by viewing a mailbox containing a message with a carefully crafted 'Expires' header. An attacker could create a malicious message that would execute arbitrary code with the privileges of the user who received it. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2665 to this issue.

Users of Elm should update to this updated package, which contains a backported patch that corrects this issue.
