Subject: [RHSA-2001:029-02] New mutt packages fix IMAP
vulnerability/incompatibility
Red Hat, Inc. Red Hat Security Advisory
Synopsis: New mutt packages fix IMAP vulnerability/incompatibility
Advisory ID: RHSA-2001:029-02
Issue date: 2001-03-09
Updated on: 2001-03-13
Product: Red Hat Linux
Keywords: mutt IMAP format string GSSAPI

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.

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>
