CVE-2017-7668 medium priority: Ubuntu including 1 source packages (apache2), 5 status rows across 5 suites (trusty, upstream, xenial, yakkety, zesty): released 4, pending 1.
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.
