    Security issues fixed with this release:
    CVE-2016-0736
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2016-1546
    The Apache HTTP Server 2.4.17 and 2.4.18, when mod_http2 is enabled,
    does not limit the number of simultaneous stream workers for a single
    HTTP/2 connection, which allows remote attackers to cause a denial of
    service (stream-processing outage) via modified flow-control windows.
    CVE-2016-2161
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2016-8740
    The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23,
    when the Protocols configuration includes h2 or h2c, does not restrict
    request-header length, which allows remote attackers to cause a denial
    of service (memory consumption) via crafted CONTINUATION frames in an
    HTTP/2 request.
    CVE-2016-8743
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
