CVE-2012-3479

Publication date 25 August 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

mdeslaur

natty is too close to EoL to be worth difficult backport, ignoring
