Jira 7.0.4 - log4j and migrated to redhat 8

[Marek]

Hi

I have Jira 7.0.4 on Centos 6

Is it possible to apply protection against log4j (Remote Code Execution - CVE-2021-44228)
no need to upgrade to a higher version of Jira?

Does the CVE-2021-44228 vulnerability exist in version Jira 7.0.4?

Can Jira 7.0.4 be migrated to redhat 8 or centos 7?
