"An updated mutt package that fixes several security bugs is now
available for Red Hat Enterprise Linux 3, 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

Mutt is a text-mode mail user agent.

A flaw was found in the way Mutt used temporary files on NFS file
systems. Due to an implementation issue in the NFS protocol, Mutt was
not able to exclusively open a new file. A local attacker could
conduct a time-dependent attack and possibly gain access to e-mail
attachments opened by a victim. (CVE-2006-5297)

A flaw was found in the way Mutt processed certain APOP authentication
requests. By sending certain responses when mutt attempted to
authenticate against an APOP server, a remote attacker could
potentially acquire certain portions of a user's authentication
credentials. (CVE-2007-1558)

A flaw was found in the way Mutt handled certain characters in gecos
fields which could lead to a buffer overflow. The gecos field is an
entry in the password database typically used to record general
information about the user. A local attacker could give themselves a
carefully crafted 'Real Name' which could execute arbitrary code if a
victim uses Mutt and expands the attackers alias. (CVE-2007-2683)

All users of mutt should upgrade to this updated package, which
contains a backported patches to correct these issues."
