(RHSA-2016:1296) Moderate: ocaml security update

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)
