What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

In Eclipse OpenJ9 versions up to 0.63, opening a supplied diagnostic dump bundle with the jdmpview tool, or equivalent DTFJ code, may cause the analyst's machine to read an arbitrary local file named inside the bundle and send its contents to an arbitrary remote host.
