Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - Red Hat Enterprise Linux - emacs: arbitrary code execution via Lisp macro expansion Ubuntu Linux - In elisp-mode.el in GNU Emacs before 30.1, 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution
