critical Nessus Plugin ID 103725

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201710-07 (OCaml: Privilege escalation)

 A bad sanitization of environment variables: CAML_CPLUGINS, CAML_NATIVE_CPLUGINS and CAML_BYTE_CPLUGINS in the OCaml compiler allows the execution of raised privileges via external code.
 Impact :

 A local attacker, by using specially crafted environment variables, could possibly escalate privileges to the root group.
 Workaround :

 There is no known workaround at this time.

Solution

All OCaml users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/ocaml-4.04.2'
