When will be the next patch for Elasticsearch?

Per Announcement Here which is being updated daily so please check back there

As of December 13, 2021, we have released Elasticsearch 6.8.21 and 7.16.1 which set the JVM option identified below and remove the vulnerable JndiLookup class from Log4j out of an abundance of caution. If you are on a 6.x version prior to 6.4.0 and upgrading is not possible, you can follow the instructions here.

In you announcement, it is stated that to mitigate the vulnerability, the -Dlog4j2.formatMsgNoLookups=true variable to the jvm.options.

However, reading the below article states that this is an insufficient mitigation measure:


Are you able to confirm if this?

Please see Apache Log4j2 Remote Code Execution (RCE) Vulnerability - CVE-2021-44228 - ESA-2021-31 as it goes into all of this in detail :slight_smile:
