Debian Security Advisory DSA 191-2 security@debian.org

Package : squirrelmail
Vulnerability : cross site scripting
Problem-Type : remote
Debian-specific: no
BugTraq ID : 5949
CVE ID : CAN-2002-1131 CAN-2002-1132

The security update for Squirrelmail (DSA 191-1) unfortunately
introduced a bug in the options page. This problem is fixed in
version 1.2.6-1.2 the current stable distribution (woody). The
unstable distribution (sid) and the old stable distribution (potato)
were not affected by this. For completeness please find below the
original security advisory:

   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.

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.
