"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)
