Recommended update for apache2

Open Source Vulnerabilities SUSE-SU-2017:2449-1

This update for apache2 provides the following fixes: Security issues fixed: * CVE-2017-9788: The value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. (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 leading to information leak or crash. (bsc#1045060) * CVE-2017-3169: mod_ssl may have dereferenced a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port leading to crash. (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) Non-security issues fixed: - Re-order cipher suites to keep exclusion list at the end. (bsc#1043484, bsc#1043607) - Remove /usr/bin/http2 link only during apache2 package uninstall, not upgrade. (bsc#1041830) - In gensslcert, use hostname when fqdn is too long. (bsc#1035829)
