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. A
user's SquirrelMail preferences could be read or modified if the user is
tricked into visiting a malicious URL. 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. 
(CAN-2005-1769)

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