the server to crash, resulting in a denial of service, or possibly perform
a Server Side Request Forgery attack. (CVE-2021-44224)

It was discovered that the Apache HTTP Server Lua module incorrectly
handled memory in the multipart parser. A remote attacker could use this
issue to cause the server to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2021-44790)

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04
