Red Hat Security Advisory 2016-1296-01 – 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, an interactive top level system, parsing tools, a replay debugger, a documentation generator, and a comprehensive library. Security Fix: 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, causing a buffer overflow. Further, arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak.
