"Several vulnerabilities have been found in the Apache HTTP server.

  - CVE-2018-17189
    Gal Goldshtein of F5 Networks discovered a denial of
    service vulnerability in mod_http2. By sending malformed
    requests, the http/2 stream for that request
    unnecessarily occupied a server thread cleaning up
    incoming data, resulting in denial of service.

  - CVE-2018-17199
    Diego Angulo from ImExHS discovered that
    mod_session_cookie does not respect expiry time.

  - CVE-2019-0196
    Craig Young discovered that the http/2 request handling
    in mod_http2 could be made to access freed memory in
    string comparison when determining the method of a
    request and thus process the request incorrectly.

  - CVE-2019-0211
    Charles Fol discovered a privilege escalation from the
    less-privileged child process to the parent process
    running as root.

  - CVE-2019-0217
    A race condition in mod_auth_digest when running in a
    threaded server could allow a user with valid
    credentials to authenticate using another username,
    bypassing configured access control restrictions. The
    issue was discovered by Simon Kappel.

  - CVE-2019-0220
    Bernhard Lorenz of Alpha Strike Labs GmbH reported that
    URL normalizations were inconsistently handled. When the
    path component of a request URL contains multiple
    consecutive slashes ('/'), directives such as
    LocationMatch and RewriteRule must account for
    duplicates in regular expressions while other aspects of
    the servers processing will implicitly collapse them."

use this issue to cause the server to consume resources, leading to a
denial of service. This issue only affected Ubuntu 18.04 LTS and
Ubuntu 18.10. (CVE-2018-17189)

It was discovered that the Apache HTTP Server incorrectly handled
session expiry times. When used with mod_session_cookie, this may
result in the session expiry time to be ignored, contrary to
expectations. (CVE-2018-17199)

Craig Young discovered that the Apache HTTP Server HTTP/2 module
incorrectly handled certain requests. A remote attacker could possibly
use this issue to cause the server to process requests incorrectly.
This issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10.

Simon Kappel discovered that the Apache HTTP Server mod_auth_digest

Bernhard Lorenz discovered that the Apache HTTP Server was

  - A denial of service (DoS) vulnerability exists in HTTP/2 steam
    handling. An unauthenticated, remote attacker can exploit this
    issue, via sending request bodies in a slow loris way to plain
    resources, to occupy a server thread. (CVE-2018-17189)

  - A vulnerability exists in mod_sesion_cookie, as it does not
    properly check the expiry time of cookies. (CVE-2018-17199) 

  - A denial of service (DoS) vulnerability exists in mod_ssl when
    used with OpenSSL 1.1.1 due to an interaction in changes to
    handling of renegotiation attempts. An unauthenticated, remote
    attacker can exploit this issue to cause mod_ssl to stop
    responding. (CVE-2019-0190)

relied only on the application's self-reported version number.");
