At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. And it is an entire ecosystem of functionality beyond text editing, including a project planner, mail and news reader, debugger interface, calendar, and more.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution.(CVE-2026-79992)\n\nA code execution flaw was found in Emacs, affecting versions prior to 31.2. The Flymake mode using language backends other than Lisp would execute arbitrary code from the edited file while performing syntax checking. Viewing or editing untrusted files using Emacs could lead to arbitrary code execution with the privileges of the user running Emacs.(CVE-2026-96442)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"emacs","purl":"pkg:rpm/openEuler/emacs&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"29.1-11.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["emacs-29.1-11.oe2403sp4.aarch64.rpm","emacs-common-29.1-11.oe2403sp4.aarch64.rpm","emacs-debuginfo-29.1-11.oe2403sp4.aarch64.rpm","emacs-debugsource-29.1-11.oe2403sp4.aarch64.rpm","emacs-devel-29.1-11.oe2403sp4.aarch64.rpm","emacs-lucid-29.1-11.oe2403sp4.aarch64.rpm","emacs-nox-29.1-11.oe2403sp4.aarch64.rpm"],"noarch":["emacs-filesystem-29.1-11.oe2403sp4.noarch.rpm","emacs-help-29.1-11.oe2403sp4.noarch.rpm","emacs-terminal-29.1-11.oe2403sp4.noarch.rpm"],"src":["emacs-29.1-11.oe2403sp4.src.rpm"],"x86_64":["emacs-29.1-11.oe2403sp4.x86_64.rpm","emacs-common-29.1-11.oe2403sp4.x86_64.rpm","emacs-debuginfo-29.1-11.oe2403sp4.x86_64.rpm","emacs-debugsource-29.1-11.oe2403sp4.x86_64.rpm","emacs-devel-29.1-11.oe2403sp4.x86_64.rpm","emacs-lucid-29.1-11.oe2403sp4.x86_64.rpm","emacs-nox-29.1-11.oe2403sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4405"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79992"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96442"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"High"}}
