    Security Advisory - RHSA-2003:120-07
    ------------------------------------------------------------------------------
    Summary:
    Updated sendmail packages fix vulnerability

    Updated Sendmail packages are available to fix a vulnerability that
    allows local and possibly remote attackers to gain root privileges.

    Description:
    Sendmail is a widely used Mail Transport Agent (MTA) which is included
    in all Red Hat Linux distributions.

    There is a vulnerability in Sendmail versions prior to and including
    8.12.8. The address parser performs insufficient bounds checking in certain
    conditions due to a char to int conversion, making it possible for an
    attacker to take control of the application. Although no exploit currently
    exists, this issue is probably locally exploitable and may also be remotely
    exploitable.

    All users are advised to update to these erratum packages containing a
    backported patch which corrects these vulnerabilities.

    Red Hat would like to thank Michal Zalewski for finding and reporting this
    issue.
