"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."

  - An access control bypass vulnerability exists in 
    mod_ssl when using per-location client certificate

In addition, Apache httpd is also affected by several additional

"This update for apache2 fixes the following issues :

CVE-2019-0220: The Apache HTTP server did not use a consistent
strategy for URL normalization throughout all of its components. In
particular, consecutive slashes were not always collapsed. Attackers
could potentially abuse these inconsistencies to by-pass access
control mechanisms and thus gain unauthorized access to protected
parts of the service. [bsc#1131241]

CVE-2019-0217: A race condition in Apache's 'mod_auth_digest' when
running in a threaded server could have allowed users with valid
credentials to authenticate using another username, bypassing
configured access control restrictions. [bsc#1131239]

CVE-2019-0211: A flaw in the Apache HTTP Server allowed
less-privileged child processes or threads to execute arbitrary code
with the privileges of the parent process. Attackers with control over
CGI scripts or extension modules run by the server could have abused
this issue to potentially gain super user privileges. [bsc#1131233]

CVE-2019-0197: When HTTP/2 support was enabled in the Apache server
for a 'http' host or H2Upgrade was enabled for h2 on a 'https' host,
an Upgrade request from http/1.1 to http/2 that was not the first
request on a connection could lead to a misconfiguration and crash.
This issue could have been abused to mount a denial-of-service attack.
Servers that never enabled the h2 protocol or that only enabled it for
https: and did not configure the 'H2Upgrade on' are unaffected.
[bsc#1131245]

CVE-2019-0196: Through specially crafted network input the Apache's
http/2 request handler could be lead to access previously freed memory
while determining the method of a request. This resulted in the
request being misclassified and thus being processed incorrectly.
[bsc#1131237]

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible

"This update for apache2 fixes the following issues :

  - CVE-2019-0220: The Apache HTTP server did not use a
    consistent strategy for URL normalization throughout all
    of its components. In particular, consecutive slashes
    were not always collapsed. Attackers could potentially
    abuse these inconsistencies to by-pass access control
    mechanisms and thus gain unauthorized access to
    protected parts of the service. [bsc#1131241]

  - CVE-2019-0217: A race condition in Apache's
    'mod_auth_digest' when running in a threaded server
    could have allowed users with valid credentials to
    authenticate using another username, bypassing
    configured access control restrictions. [bsc#1131239]

  - CVE-2019-0211: A flaw in the Apache HTTP Server allowed
    less-privileged child processes or threads to execute
    arbitrary code with the privileges of the parent
    process. Attackers with control over CGI scripts or
    extension modules run by the server could have abused
    this issue to potentially gain super user privileges.
    [bsc#1131233]

  - CVE-2019-0197: When HTTP/2 support was enabled in the
    Apache server for a 'http' host or H2Upgrade was enabled
    for h2 on a 'https' host, an Upgrade request from
    http/1.1 to http/2 that was not the first request on a
    connection could lead to a misconfiguration and crash.
    This issue could have been abused to mount a
    denial-of-service attack. Servers that never enabled the
    h2 protocol or that only enabled it for https: and did
    not configure the 'H2Upgrade on' are unaffected.
    [bsc#1131245]

  - CVE-2019-0196: Through specially crafted network input
    the Apache's http/2 request handler could be lead to
    access previously freed memory while determining the
    method of a request. This resulted in the request being
    misclassified and thus being processed incorrectly.

"This update for apache2 fixes the following issues :

  - CVE-2019-0220: The Apache HTTP server did not use a
    consistent strategy for URL normalization throughout all
    of its components. In particular, consecutive slashes
    were not always collapsed. Attackers could potentially
    abuse these inconsistencies to by-pass access control
    mechanisms and thus gain unauthorized access to
    protected parts of the service. [bsc#1131241]

  - CVE-2019-0217: A race condition in Apache's
    'mod_auth_digest' when running in a threaded server
    could have allowed users with valid credentials to
    authenticate using another username, bypassing
    configured access control restrictions. [bsc#1131239]

  - CVE-2019-0211: A flaw in the Apache HTTP Server allowed
    less-privileged child processes or threads to execute
    arbitrary code with the privileges of the parent
    process. Attackers with control over CGI scripts or
    extension modules run by the server could have abused
    this issue to potentially gain super user privileges.
    [bsc#1131233]

  - CVE-2019-0197: When HTTP/2 support was enabled in the
    Apache server for a 'http' host or H2Upgrade was enabled
    for h2 on a 'https' host, an Upgrade request from
    http/1.1 to http/2 that was not the first request on a
    connection could lead to a misconfiguration and crash.
    This issue could have been abused to mount a
    denial-of-service attack. Servers that never enabled the
    h2 protocol or that only enabled it for https: and did
    not configure the 'H2Upgrade on' are unaffected.
    [bsc#1131245]

  - CVE-2019-0196: Through specially crafted network input
    the Apache's http/2 request handler could be lead to
    access previously freed memory while determining the
    method of a request. This resulted in the request being
    misclassified and thus being processed incorrectly.
