1. Topic:

New mutt packages are available. These packages fix an instance of the common 'format string' vulnerability, and correct an incompatibilty with the current errata IMAP server.

It is recommended that all mutt users using Red Hat Linux upgrade to the new packages. The version of mutt shipped in Red Hat Linux 7.0 does not contain the format string vulnerability; it is merely a bugfix update.

Users of Red Hat Linux 6.0 and 6.1 should use the packages for Red Hat Linux 6.2. Additionally, the packages for Red Hat Linux 6.2 have support for SSL-IMAP and GSSAPI; the new packages require the openssl enhancement errata.

2. Relevant releases/architectures:

Red Hat Linux 5.2 - alpha, i386, sparc
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386

3. Problem description:

An example of a 'format string' vulnerability was present in the IMAP code in versions of mutt previous to 1.2.5. This had the effect that a compromised or malicious IMAP server could possibly execute code on the local machine.

The mutt packages in Red Hat Linux 7.0 were incompatible with the errata IMAP server released for Red Hat Linux in regards to GSSAPI authentication.

4. Solution:

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 directly *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

19326 - Updated version of Mutt (1.2) has IMAP security hole fixed
