USN-1586-1: Emacs vulnerabilities

Packages

emacs23 - The GNU Emacs editor (with GTK+ user interface)

Details

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)
