emacs24 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

Emacs could be made to run programs as your login if it
opened a specially crafted file.

Software Description:

files. If a user were tricked into opening a specially crafted file, an
attacker could possibly use this to execute arbitrary code.
