phpxmlrpc is affected by the same XML-RPC flaw as the PEAR package (bug 97399). php herd: please bump to version 1.1.1 (released on June 30, 2005).
dev-php/phpxmlrpc-1.1.1 is in portage now. I marked it stable on all arches that the previous, vulnerable version (which I pulled from the tree) was marked stable on.
Thanks Sebastian Keeping the bug open until GLSA
