CVE-2017-1000383

Published: 31 October 2017

GNU Emacs version 25.3.1 (and other versions most likely) ignores umask when creating a backup save file ("[ORIGINAL_FILENAME]~") resulting in files that may be world readable or otherwise accessible in ways not intended by the user running the emacs binary.

It really seems to not be a vulnerability. See all the comments
around this issue in emacs. I'll set it as ignored.
