sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when
configured as a CGI script (aka php-cgi), does not properly handle query
strings that lack an = (equals sign) character, which allows remote
attackers to cause a denial of service (resource consumption) by placing
command-line options in the query string, related to lack of skipping a
certain php_getopt for the βTβ case. NOTE: this vulnerability exists
because of an incomplete fix for CVE-2012-1823.
