Comment 2 Jonathan Christison 2021-02-18 16:50:35 UTC

Marking Red Hat Fuse 7, Red Hat Integration Camel-K and Red Hat Integration Service Registry as not affected as no kotlin artifacts from the vulnerable range are distributed or used.

Comment 3 Todd Cullum 2021-03-17 21:32:49 UTC

Statement:

CodeReady Studio 12 is not affected by this flaw because it ships a previous version of kotlin-stdlib without the vulnerable code present.

Red Hat Fuse 7, Red Hat Integration Camel-K and Red Hat Integration Service Registry are not affected by this flaw because no kotlin artifacts from the vulnerable range are distributed or used.
