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) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).

This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
