Date: July 27, 2020
Bugs: #719134
ID: 202007-48

Synopsis
========

An integer overflow was discovered in OCaml's standard library,
possibly allowing arbitrary execution of code.

Background
==========

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

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/ocaml < 4.09.0 >= 4.09.0

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"

References
==========
