An update that solves two vulnerabilities and has two security fixes can now be installed.

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)
