{"id":"OESA-2026-1522","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":"2026-08-18T01:19:35.823960457Z","published":"2026-03-06T11:10:32Z","upstream":["CVE-2026-28364"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1522"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28364"}],"affected":[{"package":{"name":"ocaml","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/ocaml&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.13.1-8.oe2203sp4"}]}],"ecosystem_specific":{"src":["ocaml-4.13.1-8.oe2203sp4.src.rpm"],"x86_64":["ocaml-4.13.1-8.oe2203sp4.x86_64.rpm","ocaml-debuginfo-4.13.1-8.oe2203sp4.x86_64.rpm","ocaml-debugsource-4.13.1-8.oe2203sp4.x86_64.rpm","ocaml-devel-4.13.1-8.oe2203sp4.x86_64.rpm","ocaml-help-4.13.1-8.oe2203sp4.x86_64.rpm"],"aarch64":["ocaml-4.13.1-8.oe2203sp4.aarch64.rpm","ocaml-debuginfo-4.13.1-8.oe2203sp4.aarch64.rpm","ocaml-debugsource-4.13.1-8.oe2203sp4.aarch64.rpm","ocaml-devel-4.13.1-8.oe2203sp4.aarch64.rpm","ocaml-help-4.13.1-8.oe2203sp4.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-1522.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N"}]}
