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.
