Summary
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.

When ‘enable-local-variables’’ is set to ‘:safe’, Emacs automatically processes eval forms (CVE-2012-3479). Impact : A remote attacker could entice a user to open a specially crafted file, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
