(RHSA-2004:654) squirrelmail security update

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.
