CVE-2017-7668

The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24
introduced a bug in token list parsing, which allows ap_find_token() to
search past the end of its input string. By maliciously crafting a sequence
of request headers, an attacker may be able to cause a segmentation fault,
or to force ap_find_token() to return an incorrect value.
