Following description lifted from bug filed at
https://bugs.launchpad.net/ubuntu/+source/vim/+bug/78960

<<
[EMAIL PROTECTED]:~$ rm .viminfo
[EMAIL PROTECTED]:~$ ln -s /dev/null .viminfo
[EMAIL PROTECTED]:~$ ls -l .viminfo
lrwxrwxrwx 1 sa sa 9 2007-01-12 17:16 .viminfo -> /dev/null
[EMAIL PROTECTED]:~$ umask 007
[EMAIL PROTECTED]:~$ /usr/bin/vim.basic -c 'quit'
[EMAIL PROTECTED]:~$ ls -l .viminfo
-rw-rw-rw- 1 sa sa 509 2007-01-12 17:16 .viminfo

As you can see the .viminfo file gets deleted and re-created with
permissions 666 by vim.

Note that the use of -c 'quit' is just to simplify the bug for
transcribing here -- I promise you the same thing happens if you use vim
for editing/saving a document as well.

I consider this a security bug. vim deletes a file without telling me,
and not only that but when it re-creates it, it ignores my umask by
making it world writable. This is not what I expected it to do.

I was able to confirm this bug, both in Ubuntu's
vim-gnome-7.0-164+1ubuntu7 package, and in the latest 7.1b sources.

I also have a separate question: is this an appropriate place to post
bugs? Specifically, when (a) I am interested in potential discussion
related to it, and/or (b) I am interested in possibly implementing the
fix for it? :he bugs suggests submitting bugs to [EMAIL PROTECTED], but from
the description, it sounds like those go to a single person, and are not
tracked (so, no opportunity for discussion, and it's hard to know if a
bug has been reported or what it's status is).

A subject change may be appropriate for answering this separate question.
