Subject: Closing a privilege escalation
Date: Tue, 24 Apr 2018 21:09:14 -0400	[thread overview]
Message-ID: <E1fB8vq-0002wh-19@fencepost.gnu.org> (raw)

[[[ To any NSA and FBI agents reading my email: please consider    ]]]
[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

With some arguments, emacs started inside sudo will run the user's own
.emacs file rather than root's.  This creates a known vulnerability
for privilege escalation.

I propose a feature to fix the vulnerability:

  For sudo-authorized users, require .emacs (and other Emacs startup
  files and directories) to be owned by root.

This won't be a big hassle for them, since
these users can sudo to edit their root-owned files.

Do people see any problem with this?
