CVE-2012-3479 is a vulnerability of currently unknown severity. lisp/files.el in Emacs 23.2, 23.3, 23.4, and 24.1 automatically executes eval forms in local-variable sections when the enable-local-variables option is set to :safe, which allows user-assisted remote attackers to execute arbitrary Emacs Lisp code via a crafted file.. EPSS estimates a 3.80% chance of exploitation in the next 30 days.
