Charles Fol discovered that the Apache HTTP Server incorrectly handled the
scoreboard shared memory area. A remote attacker able to upload and run
scripts could possibly use this issue to execute arbitrary code with root
privileges. (CVE-2019-0211)
It was 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 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

A flaw was found in Apache httpd. A possible regression from an earlier security fix broke behavior of MergeSlashes. The highest threat from this vulnerability is to data integrity.
Statement: This flaw was introduced when fixing https://access.redhat.com/security/cve/cve-2019-0220, therefore versions of httpd package shipped with Red Hat Enterprise Linux 7, 8 and Red Hat Software Collections are affected by this flaw.
Mitigation: This issue can be mitigated by setting the "MergeSlashes" directive to OFF
