squirrelmail - cross site scripting

Several cross site scripting vulnerabilities have been found in
squirrelmail, a feature-rich webmail package written in PHP4. The
Common Vulnerabilities and Exposures (CVE) project identified the
following vulnerabilities:

1. CAN-2002-1131: User input is not always sanitized so execution of
   arbitrary code on a client computer is possible. This can happen
   after following a malicious URL or by viewing a malicious
   addressbook entry.
2. CAN-2002-1132: Another problem could make it possible for an
   attacker to gain sensitive information under some conditions.
   When a malformed argument is appended to a link, an error page
   will be generated which contains the absolute pathname of the
   script. However, this information is available through the
   Contents file of the distribution anyway.

These problems have been fixed in version 1.2.6-1.1 for the current stable
distribution (woody) and in version 1.2.8-1.1 for the unstable
distribution (sid). The old stable distribution (potato) is not
affected since it doesn’t contain a squirrelmail package.

We recommend that you upgrade your squirrelmail package.
