Amazon Linux 2 Security Advisory: ALAS-2025-2757
Advisory Release Date: 2025-02-12 23:17 Pacific
Advisory Updated Date: 2025-02-25 10:30 Pacific
Severity:
Important
Issue Overview:
In elisp-mode.el in GNU Emacs through 30.0.92, a user who chooses to invoke elisp-completion-at-point (for code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.) (CVE-2024-53920)
Affected Packages:
emacs
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
