Red Hat Security Advisory
Synopsis: Updated SquirrelMail package fixes security vulnerability
Advisory ID: RHSA-2004:654-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2004-654.html
Issue date: 2004-12-23
Updated on: 2004-12-23
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-1036
- - ---------------------------------------------------------------------
1. Summary:
An updated SquirrelMail package that fixes a cross-site scripting
vulnerability is now available.
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
3. Problem description:
SquirrelMail is a webmail package written in PHP.
A cross-site scripting bug has been found in SquirrelMail. This issue
could allow an attacker to send a mail with a carefully crafted header,
which could result in causing the victim's machine to execute a malicious
script. The Common Vulnerabilities and Exposures project has assigned the
name CAN-2004-1036 to this issue.
Additionally, the following issues have been addressed:
- - - updated splash screens
- - - HIGASHIYAMA Masato's patch to improve Japanese support
- - - real 1.4.3a tarball
- - - config_local.php and default_pref in /etc/squirrelmail/ to match upstream
RPM.
Please note that it is possible that upgrading to this package may remove
your SquirrelMail configuration files due to a bug in the RPM package.
Upgrading will prevent this from happening in the future.
Users of SquirrelMail are advised to upgrade to this updated package which
contains a patched version of SquirrelMail version 1.43a and is not
vulnerable to 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
