An update for ocaml is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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) :

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each

OCaml is a high-level, strongly-typed, functional, and object-oriented

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)"
