The extract function in PHP before 5.2.15 does not prevent use of the
EXTR_OVERWRITE parameter to overwrite (1) the GLOBALS superglobal array and
(2) the this variable, which allows context-dependent attackers to bypass
intended access restrictions by modifying data structures that were not
intended to depend on external input, a related issue to CVE-2005-2691 and
CVE-2006-3758.
