Details

It was discovered that the Apache HTTP Server incorrectly handled certain
forward proxy requests. A remote attacker could use this issue to cause
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)

Update instructions

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

Ubuntu 21.10
Ubuntu 21.04

In general, a standard system update will make all the necessary changes.
