1. Topic:

New mutt packages that fix an overflow in mutt's address parsing code are
available. It is recommended that all mutt users update to the fixed packages.

2. Problem description:

An overflow exists in mutt's RFC822 address parser. A remote attacker
could send a carefully crafted email message which when read by mutt would
be able to overwrite arbitrary bytes in memory. The updated mutt-1.2.5.1
release fixes the problem. Thanks go to Joost Pol for discovering the
bug and the Mutt team for the fixed release.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0001 to this issue.

3. Bug IDs fixed: (see bugzilla for more information)

4. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386, sparc
Red Hat Linux 7.0J - i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64, s390

5. RPMs required:

6. 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 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.

7. Verification:

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:

You can verify each package with the following command: rpm --checksig filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg filename

Note that you need RPM >= 3.0 to check GnuPG keys.
