Red Hat Linux Advisory: pine

Red Hat Security Advisory

1. Topic:

Updated Pine packages that resolve remotely exploitable security
issues are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.1 – i386
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:

Pine, developed at the University of Washington, is a tool for
reading, sending, and managing electronic messages (including mail
and news).

A buffer overflow exists in the way unpatched versions of Pine
prior to 4.57 handle the ‘message/external-body’ type. The Common
Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name
CAN-2003-0720 to this issue.

An integer overflow exists in the Pine MIME header parsing in
versions prior to 4.57. The Common Vulnerabilities and Exposures
project (cve.mitre.org/) has
assigned the name CAN-2003-0721 to this issue.

Both of these flaws could be exploited by a remote attacker
sending a carefully crafted email to the victim that will execute
arbitrary code when the email is opened using Pine.

All users of Pine are advised to upgrade to these erratum
packages, which contain a backported security patch correcting
these issues.

Red Hat would like to thank iDefense for bringing these issues
to our attention and the University of Washington for the
patch.

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>
