   An update that fixes 9 vulnerabilities is now available.

Description:

   This update for apache2 fixes the following issues:

   - Allow disabling SNI on proxy connections using "SetEnv proxy-disable-sni
     1" in the configuration files. (bsc#1052830)
   - Allow ECDH again in mod_ssl, it had been incorrectly disabled with the
     2.2.34 update. (bsc#1064561)

   Following security issue has been fixed:

   - CVE-2017-9798: A use-after-free in the OPTIONS command could be used by
     attackers to disclose memory of the apache server process, when htaccess
     uses incorrect Limit statement. (bsc#1058058)

   Additionally, references to the following security issues, fixed by the
   previous version-update of apache2 to Apache HTTPD 2.2.34 have been added:

   - CVE-2017-7668: The HTTP strict parsing introduced a bug in token list
     parsing, which allowed ap_find_token() to search past the end of its
     input string. By maliciously crafting a sequence of request headers, an
     attacker may have be able to cause a segmentation fault, or to force
     ap_find_token() to return an incorrect value. (bsc#1045061)
   - CVE-2017-3169: mod_ssl may have de-referenced 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)
   - 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)
