Synopsis:          Moderate: imap security update
Advisory ID:       RHSA-2005:128-01
Advisory URL:      https://access.redhat.com/errata/RHSA-2005:128.html
Issue date:        2005-02-23
Updated on:        2005-02-23
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2005-0198
- ---------------------------------------------------------------------1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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
 CAN-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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:
