lhotari opened a new pull request #186:
URL: https://github.com/apache/pulsar-helm-chart/pull/186
### Motivation
CVE-2021-44228 , a severe RCE for Log4J.
The workaround is to set `-Dlog4j2.formatMsgNoLookups=true` system property.
CVE-2021-44228 is triggered if user provided input is passed to Logger's
debug/info/warn/error method directly. It doesn't get triggered if user
provided input is logged using {} placeholders. This reduces the likelyhood of
the exploit quite a lot.
### Modifications
Add `OPTS="${OPTS} -Dlog4j2.formatMsgNoLookups=true"` prefix to calls to
`exec bin/pulsar` and `exec bin/bookkeeper` . This results in
`-Dlog4j2.formatMsgNoLookups=true` system property getting set.
