    Synopsis
    ========

    There is a format string flaw in Pound, allowing remote execution of
    arbitrary code with the rights of the Pound process.

    Background
    ==========

    Pound is a reverse proxy, load balancer and HTTPS front-end. It allows
    to distribute the load on several web servers and offers a SSL wrapper
    for web servers that do not support SSL directly.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-www/pound <= 1.5 >= 1.6

    Description
    ===========

    A format string flaw in the processing of syslog messages was
    discovered and corrected in Pound.

    Impact
    ======

    This flaw may allow remote execution of arbitrary code with the rights
    of the Pound daemon process. By default, Gentoo uses the "nobody" user
    to run the Pound daemon.

    Workaround
    ==========

    There is no known workaround at this time. All users are advised to
    upgrade to the latest available version of Pound.

    Resolution
    ==========

    All users of Pound should upgrade to the latest stable version:

        # emerge sync

        # emerge -pv ">=net-www/pound-1.6"
        # emerge ">=net-www/pound-1.6"
