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 < 4.04.2 >= 4.04.2 Description =========== 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. Resolution ========== All OCaml users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/ocaml-4.04.2" References ========== [ 1 ] CVE-2017-9772 https://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-9772 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201710-07 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
