27 Nov 2024 — 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.) In elisp-mode.el in GNU Emacs before 30.1, a user who chooses to invoke elisp-completion-at-point (for code completion) on un... • https://eshelyaron.com/posts/2024-11-27-emacs-aritrary-code-execution-and-how-to-avoid-it.html • CWE-94: Improper Control of Generation of Code ('Code Injection') •

26 Nov 2024 — The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with... • https://bugzilla.mozilla.org/show_bug.cgi?id=1929600 • CWE-347: Improper Verification of Cryptographic Signature CWE-354: Improper Validation of Integrity Check Value •

21 Nov 2024 — A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs. An update for avahi is now available for Red Hat Enterprise Linux 9. • https://access.redhat.com/security/cve/CVE-2024-52616 • CWE-334: Small Space of Random Values •
