Summary
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)

Vulnerabilities 4
-
Unscored —CVE-2022-22719 EPSS 70%
mod_lua Use of uninitialized value of in r:parsebody
A carefully crafted request body can cause a read to a random memory area which could cause the process to crash. This issue affects Apache HTTP Server 2.4.52 and earlier.

HTTP request smuggling vulnerability in Apache HTTP Server 2.4.52 and earlier
Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling
-
Unscored —CVE-2022-22721 EPSS 42%
core: Possible buffer overflow with very large or unlimited LimitXMLRequestBody
If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier.
-
Unscored —
mod_sed: Read/write beyond bounds
Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
