An updated elm package is now available that fixes a buffer overflow issue
for Red Hat Enterprise Linux 2.1 AS and AW.

Elm is a terminal mode email client.

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
