Package        : squirrelmail
Vulnerability  : cross site scripting
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2002-1341
BugTraq Id     : 6302

A cross site scripting vulnerability has been discovered in
squirrelmail, a feature-rich webmail package written in PHP4.
Squirrelmail doesn't sanitize user provided variables in all places,
leaving it vulnerable to a cross site scripting attack.

For the current stable distribution (woody) this problem has been
fixed in version 1.2.6-1.3.  The old stable distribution (potato) is
not affected since it doesn't contain a squirrelmail package.

An updated package for the current unstable distribution (sid) is
expected soon.

We recommend that you upgrade your squirrelmail package.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
