      Confirm Command Execution Vulnerability
    ------------------------------------------------------------------------

    SUMMARY

     <http://freshmeat.net/projects/confirm/> Confirm is "a simple procmail
    script that uses a pattern-matching auto-whitelist to help identify
    unsolicited email". A critical security flaw was found in Confirm 0.62 and
    below that allows a remote user to craft a unique e-mail that will execute
    a command on the local system using the credentials of the user running
    confirm.

    DETAILS

    Vulnerable Systems:
     * Confirm version 0.62 and prior

    Immune Systems:
     * Confirm version 0.70

    Due to insufficient user supplied data filtering, emails containing
    special characters, like ",`,|,;,$ and so on in headers trick Confirm and
    lead to command execution.

    How to patch:
    Install confirm-0.70 from:
    <http://hr.uoregon.edu/davidrl/confirm/confirm-0.70.tgz>
    http://hr.uoregon.edu/davidrl/confirm/confirm-0.70.tgz.
