    Synopsis
    ========

    IPsec-Tools' racoon is affected by a remote Denial of Service
    vulnerability.

    Background
    ==========

    IPsec-Tools is a port of KAME's implementation of the IPsec utilities.
    It contains a collection of network monitoring tools, including racoon,
    ping, and ping6.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-firewall/ipsec-tools < 0.5-r1 *>= 0.4-r1
    >= 0.5-r1

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

    Sebastian Krahmer has reported a potential remote Denial of Service
    vulnerability in the ISAKMP header parsing code of racoon.

    Impact
    ======

    An attacker could possibly cause a Denial of Service of racoon using a
    specially crafted ISAKMP packet.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All IPsec-Tools users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.4-r1"
