CVE-2012-3479: GNU Emacs

Medium severity, CVSS 6.8. EPSS: 3.8% chance of exploitation in the next 30 days.

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.

Affected products

• GNU Emacs: version 23.2 only; version 23.3 only; version 23.4 only; version 24.1 only
