CVE-2005-3389

The parse_str function in PHP 4.x up to 4.4.0 and 5.x up to 5.0.5, when
called with only one parameter, allows remote attackers to enable the
register_globals directive via inputs that cause a request to be terminated
due to the memory_limit setting, which causes PHP to set an internal flag
that enables register_globals and allows attackers to exploit
vulnerabilities in PHP applications that would otherwise be protected.
