Several security issues were fixed in Apache HTTP Server.

Software Description:
- apache2: Apache HTTP server

Details:

USN-5333-1 fixed several vulnerabilities in Apache. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

Original advisory 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.

 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 16.04 ESM:
  apache2                         2.4.18-2ubuntu3.17+esm5
  apache2-bin                     2.4.18-2ubuntu3.17+esm5

Ubuntu 14.04 ESM:
  apache2                         2.4.7-1ubuntu4.22+esm4
  apache2-bin                     2.4.7-1ubuntu4.22+esm4

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