Amazon Linux AMI : log4j-cve-2021-44228-hotpatch (ALAS-2021-1554)

high Nessus Plugin ID 156264

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of log4j-cve-2021-44228-hotpatch installed on the remote host is prior to 1.1-13. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1554 advisory.

 The Apache Log4j hotpatch package starting with log4j-cve-2021-44228-hotpatch-1.1-13 will now explicitly mimic the permissions of the JVM attempting to be updated.

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update log4j-cve-2021-44228-hotpatch' to update your system.
