A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in Apache HTTP Server.

Software Description:
- apache2: Apache HTTP server

Details:

Chamal De Silva discovered that the Apache HTTP Server mod_lua module
incorrectly handled certain crafted request bodies. A remote attacker could
possibly use this issue to cause the server to crash, resulting in a denial
of service. (CVE-2022-22719)

James Kettle discovered that the Apache HTTP Server incorrectly closed
inbound connection when certain errors are encountered. A remote attacker
could possibly use this issue to perform an HTTP Request Smuggling attack.
(CVE-2022-22720)

It was discovered that the Apache HTTP Server incorrectly handled large
LimitXMLRequestBody settings on certain platforms. In certain
configurations, 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-2022-22721)

Ronald Crane discovered that the Apache HTTP Server mod_sed module
incorrectly handled memory. 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-2022-23943)

Update instructions:

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

Ubuntu 21.10:
  apache2                         2.4.48-3.1ubuntu3.3
  apache2-bin                     2.4.48-3.1ubuntu3.3

Ubuntu 20.04 LTS:
  apache2                         2.4.41-4ubuntu3.10
  apache2-bin                     2.4.41-4ubuntu3.10

Ubuntu 18.04 LTS:
  apache2                         2.4.29-1ubuntu4.22
  apache2-bin                     2.4.29-1ubuntu4.22
