Description

Hiroshi Oota discovered that Emacs incorrectly handled search paths. If a user were tricked into opening a file with Emacs, a local attacker could execute arbitrary Lisp code with the privileges of the user invoking the program. (CVE-2012-0035)

Paul Ling discovered that Emacs incorrectly handled certain eval forms in local-variable sections. If a user were tricked into opening a specially crafted file with Emacs, a remote attacker could execute arbitrary Lisp code with the privileges of the user invoking the program. (CVE-2012-3479).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
