   An update that solves 5 vulnerabilities and has three fixes
   is now available.

Description:

   This update for apache2 fixes several issues.

   These security issues were fixed:

   - CVE-2017-9798: Prevent use-after-free use of memory that allowed for an
     information leak via OPTIONS (bsc#1058058)
   - CVE-2017-9788: Uninitialized memory reflection in mod_auth_digest could
     have lead to leakage of potentially confidential information, and a
     segfault in
     other cases resulting in DoS (bsc#1048576).
   - 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).
   - CVE-2017-3169: mod_ssl may dereferenced 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).

   These non-security issues were fixed:

   - remove /usr/bin/http2 symlink only during apache2 package uninstall, not
     upgrade (bsc#1041830)
   - gensslcert: use hostname when fqdn is too long (bsc#1035829)
   - add NotifyAccess=all to service file (bsc#980663)
