SUSE SLES12 Security Update : Recommended update for apache2 (SUSE-SU-2017:2449-1)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

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)
