Rocky Linux 8 : httpd:2.4 (RLSA-2021:1809)

critical Nessus Plugin ID 184496

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:1809 advisory.

- In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. (CVE-2018-17199)

- Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE (CVE-2020-11984)

- Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above info will mitigate this vulnerability for unpatched servers. (CVE-2020-11993)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
