Mitigation for CVE-2021-44228 (Log4j)
Code42 App Version 8.8.1 Update
On December 14, 2021 Code42 app version 8.8.1 was released, mitigating CVE-2021-44228 along with other bug and security enhancements.
Since the patched version of Log4j (2.15) was released, there has been a new version of log4j that remediates additional vulnerabilities. We have assessed this new version and determined it does not remediate vulnerabilities for our environment and therefore, we will not be doing an emergency patch to apply 2.16. Version 2.15 addresses the critical vulnerability. The 2.16 version addresses a very specific edge case related to a logging configuration that we do not use in our product. As always, we will be monitoring for updated versions and apply those versions as necessary.

On Wednesday, December 15, 2021, Code42 released updates to its cloud infrastructure to remediate CVE-2021-44228. This release also includes features, enhancements and other minor updates and bug fixes. For full details, view the release notes.
