{"id":"OESA-2026-1525","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.\r\n\r\nSecurity Fix(es):\n\nIn 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)","modified":"2026-03-06T13:15:13.344407Z","published":"2026-03-06T12:43:22Z","upstream":["CVE-2026-28364"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1525"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28364"}],"affected":[{"package":{"name":"ocaml","ecosystem":"openEuler:24.03-LTS-SP2","purl":"pkg:rpm/openEuler/ocaml&distro=openEuler-24.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.14.1-6.oe2403sp2"}]}],"ecosystem_specific":{"src":["ocaml-4.14.1-6.oe2403sp2.src.rpm"],"x86_64":["ocaml-4.14.1-6.oe2403sp2.x86_64.rpm","ocaml-debuginfo-4.14.1-6.oe2403sp2.x86_64.rpm","ocaml-debugsource-4.14.1-6.oe2403sp2.x86_64.rpm","ocaml-devel-4.14.1-6.oe2403sp2.x86_64.rpm","ocaml-help-4.14.1-6.oe2403sp2.x86_64.rpm"],"aarch64":["ocaml-4.14.1-6.oe2403sp2.aarch64.rpm","ocaml-debuginfo-4.14.1-6.oe2403sp2.aarch64.rpm","ocaml-debugsource-4.14.1-6.oe2403sp2.aarch64.rpm","ocaml-devel-4.14.1-6.oe2403sp2.aarch64.rpm","ocaml-help-4.14.1-6.oe2403sp2.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-1525.json"}}],"schema_version":"1.7.3"}
