Description Jan Lieskovsky 2012-05-21 10:20:58 UTC
A security flaw was found in the way the com_print_typeinfo() routine of the PHP scripting language processed certain COM object arguments. If a PHP language based application remotely accepted untrusted com_print_typeinfo() arguments in order to print out a PHP class definition for a dispatchable interface, a remote attacker could provide a specially-crafted COM object, which once processed by the application could lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application.
