Drake Wilson discovered that Emacs did not correctly handle the safe mode of ‘enable-local-variables’. If a user were tricked into opening a specially crafted file while ‘enable-local-variables’ was set to the non-default ‘:safe’, a remote attacker could execute arbitrary commands with the user’s privileges.

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.
