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

Description:

   This update for apache2 fixes several issues.

   These security issues were fixed:

   - CVE-2017-9789: When under stress (closing many connections) the HTTP/2
     handling code would sometimes access memory after it has been freed,
     resulting in potentially erratic behaviour (bsc#1048575).
   - CVE-2017-7659: A maliciously constructed HTTP/2 request could cause
     mod_http2 to dereference a NULL pointer and crash the server process
     (bsc#1045160).

   These non-security issues were fixed:

   - Use the full path to a2enmod and a2dismod in the apache-22-24-upgrade
     script (bsc#1042037)
   - Fall back to 'localhost' as hostname in gensslcert (bsc#1057406)
