    An update that solves four vulnerabilities and has 9 fixes is now available.

    Description:


    The Apache2 webserver was updated to fix several issues:

    Security issues fixed:
    - The chunked transfer coding implementation in the Apache HTTP Server did
    not properly parse chunk headers, which allowed remote attackers to
    conduct HTTP request smuggling attacks via a crafted request, related to
    mishandling of large chunk-size values and invalid chunk-extension
    characters in modules/http/http_filters.c. [bsc#938728, CVE-2015-3183]
    - The LOGJAM security issue was addressed by: [bnc#931723 CVE-2015-4000]
    * changing the SSLCipherSuite cipherstring to disable export cipher
    suites and deploy Ephemeral Elliptic-Curve Diffie-Hellman (ECDHE)
    ciphers.
    * Adjust 'gensslcert' script to generate a strong and unique Diffie
    Hellman Group and append it to the server certificate file.
    - The ap_some_auth_required function in server/request.c in the Apache
    HTTP Server 2.4.x did not consider that a Require directive may be
    associated with an authorization setting rather than an authentication
    setting, which allowed remote attackers to bypass intended access
    restrictions in opportunistic circumstances by leveraging the presence
    of a module that relies on the 2.2 API behavior. [bnc#938723 bnc#939516
    CVE-2015-3185]
    - Tomcat mod_jk information leak due to incorrect JkMount/JkUnmount
    directives processing [bnc#927845 CVE-2014-8111]

    Other bugs fixed:
    - Now provides a suse_maintenance_mmn_# [bnc#915666].
    - Hardcoded modules in the %files [bnc#444878].
    - Fixed the IfModule directive around SSLSessionCache [bnc#911159].
    - allow only TCP ports in Yast2 firewall files [bnc#931002]
    - fixed a regression when some LDAP searches or comparisons might be done
    with the wrong credentials when a backend connection is reused
    [bnc#930228]
    - Fixed split-logfile2 script [bnc#869790]
    - remove the changed MODULE_MAGIC_NUMBER_MINOR from which confuses modules
    the way that they expect functionality that our apache does not provide
    [bnc#915666]
    - gensslcert: CN now defaults to `hostname -f` [bnc#949766], fix help
    [bnc#949771]
