1. Summary:

An updated squirrelmail package that fixes two security issues is now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

[Updated 04 Aug 2005]
The previous SquirrelMail package released with this errata contained a bug
which rendered the addressbook unusable. The erratum has been updated with
a package which corrects this issue.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - noarch
Red Hat Desktop version 3 - noarch
Red Hat Enterprise Linux ES version 3 - noarch
Red Hat Enterprise Linux WS version 3 - noarch
Red Hat Enterprise Linux AS version 4 - noarch
Red Hat Enterprise Linux Desktop version 4 - noarch
Red Hat Enterprise Linux ES version 4 - noarch
Red Hat Enterprise Linux WS version 4 - noarch

3. Problem description:

SquirrelMail is a standards-based webmail package written in PHP4.

A bug was found in the way SquirrelMail handled the $_POST variable. If a
user is tricked into visiting a malicious URL, the user's SquirrelMail
preferences could be read or modified. The Common Vulnerabilities and
Exposures project assigned the name CAN-2005-2095 to this issue.

Several cross-site scripting bugs were discovered in SquirrelMail. An
attacker could inject arbitrary Javascript or HTML content into
SquirrelMail pages by tricking a user into visiting a carefully crafted
URL, or by sending them a carefully constructed HTML email message. The
Common Vulnerabilities and Exposures project assigned the name
CAN-2005-1769 to this issue. 

All users of SquirrelMail should upgrade to this updated package, which
contains backported patches that resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:

    http://www.redhat.com/docs/manuals/enterprise/

Additionally, users will have to bring up the "Network Proxy" dialog and
reset their keys for the settings to take place.

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

160241 - CAN-2005-1769 Multiple XSS issues in squirrelmail
162275 - CAN-2005-2095 squirrelmail cross site posting issue
