This update for apache2 provides the following fixes: Security issues fixed :
CVE-2016-0736: Protect mod_session_crypto data with a MAC to prevent padding oracle attacks (bsc#1016712).
CVE-2016-2161: Malicious input to mod_auth_digest could have caused the server to crash, resulting in DoS (bsc#1016714).
CVE-2016-8743: Added new directive ‘HttpProtocolOptions Strict’ to avoid proxy chain misinterpretation (bsc#1016715). Bugfixes :
Add NotifyAccess=all to systemd service files to prevent warnings in the log when using mod_systemd (bsc#980663).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
