NVD Description

Note: Versions mentioned in the description apply only to the upstream emacs-lucid package and not the emacs-lucid package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

A 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.
