No versions of an Amazon Linux Java Virtual Machine are affected by CVE-2021-44228 or CVE-2021-45046. However, if customers load a log4j version that is affected by CVE-2021-44228 or CVE-2021-45046 into an Amazon Linux JVM, it will introduce the issues identified in CVE-2021-44228 and CVE-2021-45046 into the JVM. This update modifies Amazon Linux packages that provide a JVM to also install the AWS-developed hotpatch to mitigate CVE-2021-44228 or CVE-2021-45046 by default. For more information on the hotpatch package in Amazon Linux, see https://alas.aws.amazon.com/announcements/2021-001.html
