Summary
ocaml security update
Details

OCaml is a high-level, strongly-typed, functional and object-oriented programming language from the ML family of languages. This package includes runtime environment, X11 support ,Documentation generator and emacs.

Security Fix(es):

In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization (runtime/intern.c) enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock() function, which performs unbounded memcpy() operations using attacker-controlled lengths from crafted Marshal data.(CVE-2026-28364)
