Background

OCaml is a high-level, strongly-typed, functional, and object-oriented programming language from the ML family of languages

Description

The caml_ba_deserialize function in byterun/bigarray.c in the standard library of OCaml has an integer overflow.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All OCaml users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-lang/ocaml-4.09.0"
OSVersionArchitecturePackageVersionFilename
Gentooanyalldev-lang/ocaml< 4.09.0UNKNOWN
