(bsc#1058058) Additionally, references to the following security issues, fixed by the previous version-update of apache2 to Apache HTTPD 2.2.34 have been added :
- CVE-2017-7668: The HTTP strict parsing introduced a bug in token list parsing, which allowed ap_find_token() to search past the end of its input string.

(bsc#1045061)
- CVE-2017-3169: mod_ssl may have de-referenced a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port allowing for DoS. (bsc#1045062)
- CVE-2017-3167: Use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may have lead to authentication requirements being bypassed. (bsc#1045065)
- CVE-2017-7679: mod_mime could have read one byte past the end of a buffer when sending a malicious Content-Type response header. (bsc#1045060)
