RHSA-2005-128: imap

Vulnerability Assessment Summary
Check for the version of the imap packages

Detailed Explanation for this Vulnerability Assessment

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
permit 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.
