Arbitrary Code Execution via Crafted File in Emacs Lisp

CVE-2012-3479 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

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.
