Product: Red Hat Linux
Keywords: mutt menu crash
Cross references:
Obsoletes:
CVE Names: CAN-2004-0078
1. Topic:
New mutt packages that fix a remotely-triggerable crash in the
menu drawing code are now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
Mutt is a text-mode mail user agent.
A bug was found in the index menu code in versions of mutt. A
remote attacker could send a carefully crafted mail message that
can cause mutt to segfault and possibly execute arbitrary code as
the victim. The Common Vulnerabilities and Exposures project
(cve.mitre.org/) has assigned
the name CAN-2004-0078 to this issue.
It is recommended that all mutt users upgrade to these updated
packages, which contain a backported security patch and are not
vulnerable to this issue.
Red Hat would like to thank Niels Heinen for reporting 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 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.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the up2date
client with an updated certificate. The latest version of up2date
is available from the Red Hat FTP site and may also be downloaded
directly from the RHN website:

These packages are GPG signed by Red Hat for security. Our key
is available from https://www.redhat.com/security/keys.html
You can verify each package with the following command:
rpm –checksig -v <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:
md5sum <filename>
