Bug #66112 [NEW]: Use after free condition in SOAP extension (segfault)

From: martin dot koegler at brz dot gv dot at Operating system: Any PHP version: 5.5.6 Package: SOAP related Bug Type: Bug Bug description:Use after free condition in SOAP extension (segfault) Description: ------------ do_soap_call (ext/soap/soap.c) saves the values of SOAP_GLOBAL(typemap) (and other variables) and overrides them. After doing its work, it restores the old values. If the code in between invokes zend_bailout (eg. because of an error/exception), the zend_bailout is catched after the restore of the values. So SOAP_GLOBAL(typemap) is not restored. The remaining code executes using a invalid, potential freed typemap.
