---------------------------------------------------------------------
Fedora Legacy Update Advisory

Synopsis: Updated imap packages fix security issues
Advisory ID: FLSA:152912
Issue date: 2005-05-12
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CAN-2003-0297 CAN-2005-0198
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated imap packages that fix security issues are now available.

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

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

A buffer overflow flaw was found in the c-client IMAP client. An attacker could create a malicious IMAP server that if connected to by a victim could execute arbitrary code on the client machine. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0297 to this issue.

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.

Users of imap are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
