    Synopsis
    ========

    The jabberd server was found to be vulnerable to a remote Denial of
    Service attack.

    Background
    ==========

    Jabber is a set of streaming XML protocols enabling message, presence,
    and other structured information exchange between two hosts. jabberd is
    the original implementation of the Jabber protocol server.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-im/jabberd <= 1.4.3-r3 >= 1.4.3-r4

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

    Jose Antonio Calvo found a defect in routines handling XML parsing of
    incoming data. jabberd 1.x may crash upon reception of invalid data on
    any socket connection on which XML is parsed.

    Impact
    ======

    A remote attacker may send a specific sequence of bytes to an open
    socket to crash the jabberd server, resulting in a Denial of Service.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All jabberd users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=net-im/jabberd-1.4.3-r4"
        # emerge ">=net-im/jabberd-1.4.3-r4"
