---------------------------------------------------------------------

1. Topic:

New Balsa, Mutt, and libesmtp packages that fix potential buffer overflow
vulnerabilities are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

Mutt is a text-mode email client. Balsa is a GNOME email client which
includes code from Mutt.

A potential buffer overflow in Mutt version 1.4 exists when parsing mailbox
names returned by an IMAP server. It is possible that a hostile IMAP server
could cause arbitrary code to be executed by the user running Mutt.  This
issue affects versions of Mutt provided with Red Hat Linux 8.0 and Red Hat
Linux 9.

Versions 1.2 and higher of Balsa incorporate the vulnerable Mutt IMAP code
and are therefore vulnerable to this issue as well.  It is possible that a
hostile IMAP server could cause arbitrary code to be executed by the user
running Balsa.  This issue affects Red Hat Linux 7.2, 7.3, 8.0 and 9.

Additionally, a buffer overflow in libesmtp, an SMTP library used by Balsa,
before version 0.8.11 allows a hostile remote SMTP server to execute
arbitrary code via a certain response or cause a denial of service via long
server responses.  This issue only affects versions of libesmtp provided by
Red Hat Linux 7.2 and 7.3.

Users of Mutt and Balsa are recommended to update to these erratum packages
containing updated versions of Mutt, Balsa, and libesmtp which are not
vulnerable to these issues.

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.

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