Logger crasher

My server has been spitting out weird logging messages and then crashed. My admin then send me a link to reddit where people call it the "logger crasher". Many servers are under attack!

So if you use this: https://github.com/welk1n/JNDI-Injection-Exploit and attack servers it crashes. Someone posted a link to this https://issues.apache.org/jira/projects/LOG4J2/issues/LOG4J2-3201

so if it is fixed in 2.15.0 please update your logger4j in 1.18.1, my server is under attack and I can't do anything!
