A new patch for OCaml on Red Hat Enterprise Linux 7 resolves moderate-risk vulnerabilities, among which is a possible buffer overflow.
An update for ocaml is now available for Red Hat Enterprise Linux 7

Solution

https://access.redhat.com/articles/11258

Summary

OCaml is a high-level, strongly-typed, functional, and object-oriented programming language from the ML family of languages. The ocaml packages contain two batch compilers (a fast bytecode compiler and an optimizing native-code compiler), an interactive top level system, parsing tools (Lex, Yacc, Camlp4), a replay debugger, a documentation generator, and a comprehensive library.
Security Fix(es):
* OCaml versions 4.02.3 and earlier have a runtime bug that, on 64-bit platforms, causes size arguments to internal memmove calls to be sign-extended from 32- to 64-bits before being passed to the memmove function. This leads to arguments between 2GiB and 4GiB being interpreted as larger than they are (specifically, a bit below 2^64), causing a buffer overflow. Further, arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak. (CVE-2015-8869)
