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

1. Topic:

Updated squirrelmail packages are now available for Red Hat Linux.

2. Relevant releases/architectures:

Red Hat Linux 8.0 - noarch

3. Problem description:

SquirrelMail is a webmail package written in PHP.  Two
vulnerabilities have been found that affect versions of SquirrelMail
shipped with Red Hat Linux 8.0.

A cross-site scripting (XSS) vulnerability in Squirrelmail version
1.2.10 and earlier allows remote attackers to execute script as other
web users via read_body.php. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2002-1341 to this
issue.

An incomplete fix for a cross-site scripting vulnerability in
SquirrelMail 1.2.8 calls the strip_tags function on the PHP_SELF
value but does not save the result back to that variable, leaving it
open to cross-site scripting attacks. (CAN-2002-1276)

All users of Squirrelmail are advised to upgrade to these packages
based on SquirrelMail version 1.2.10 which contain a backported patch
to fix 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):

78982 - SquirrelMail 1.2.8 vulnerable to XSS attacks
79147 - SquirrelMail 1.2.8 vulnerable to XSS attacks

6. RPMs required:

Red Hat Linux 8.0:

SRPMS:
ftp://updates.redhat.com/8.0/en/os/SRPMS/squirrelmail-1.2.10-1.src.rpm

noarch:
ftp://updates.redhat.com/8.0/en/os/noarch/squirrelmail-1.2.10-1.noarch.rpm



7. Verification:

MD5 sum                          Package Name

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>
