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

      These files will probably be moved into the stable distribution on
      its next revision.
