apache2 vulnerabilities
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. (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)
