    Synopsis
    ========

    The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to
    execute arbitrary PHP script commands.

    Background
    ==========

    The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations
    of the XML-RPC protocol.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-php/PEAR-XML_RPC < 1.3.1 >= 1.3.1
      2 dev-php/phpxmlrpc < 1.1.1 >= 1.1.1
        -------------------------------------------------------------------
         2 affected packages on all of their supported architectures.
        -------------------------------------------------------------------

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

    James Bercegay of GulfTech Security Research discovered that the PEAR
    XML-RPC and phpxmlrpc libraries fail to sanatize input sent using the
    "POST" method.

    Impact
    ======

    A remote attacker could exploit this vulnerability to execute arbitrary
    PHP script code by sending a specially crafted XML document to web
    applications making use of these libraries.

    Workaround
    ==========

    There are no known workarounds at this time.

    Resolution
    ==========

    All PEAR-XML_RPC users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-php/PEAR-XML_RPC-1.3.1"

    All phpxmlrpc users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.1.1"
