    During a code review of the hfaxd server, the SuSE Security Team discovered
    a format bug condition that allows a remote attacker to execute arbitrary
    code as the root user.  However, the bug cannot be triggered in the default
    hylafax configuration.

    the latest available version.  Vulnerable versions of hylafax have been
    removed from portage.  Specific steps to upgrade:

    # emerge sync
    # emerge -pv '&gt;=net-misc/hylafax-4.1.8'
    # emerge '&gt;=net-misc/hylafax-4.1.8'
    # emerge clean</code>
