RHEL 3 : imap (RHSA-2005:128)

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated imap packages to correct a security vulnerability in CRAM-MD5
authentication are now available for Red Hat Enterprise Linux 3.

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

The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access
protocols.

A logic error in the CRAM-MD5 code in the University of Washington
IMAP (UW-IMAP) server was discovered. When Challenge-Response
Authentication Mechanism with MD5 (CRAM-MD5) is enabled, UW-IMAP does
not properly enforce all the required conditions for successful
authentication, which could allow remote attackers to authenticate as
arbitrary users. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0198 to this issue.

All users of imap should upgrade to these updated packages, which
contain a backported patch and are not vulnerable to this issue.
