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”
