Unless you can control the environment an prevent use of CAML_CPLUGINS and CAML_NATIVE_CPLUGINS I'm not sure there's any except avoiding using the compilers above. Note that the escalation affects only setuid binaries.
For reference here's the discussion about the bug:
https://caml.inria.fr/mantis/view.php?id=7557
the commit that introduced the vulnerability:
https://github.com/ocaml/ocaml/pull/668/commits/6a83bdd5937522efeeff496349c22bcb2f832866
and the resolution:
https://github.com/ocaml/ocaml/commit/850021c200c7507f2a928a66fa1291ff4ae3a622

Best,
