view-lossage and passwords

view-lossage and passwords

[mandar.mitra]

At various times (e.g. when I am using a terminal) within emacs, I
need to enter my password. This is, by default, stored in my typing
history, and becomes visible with view-lossage. Is there some way to
prevent passwords from being recorded in typing history, so that if I
run view-lossage (usually accidentally), my password won't show up on
screen?

I've looked around on the web a bit, but didn't find anything that
addresses this. Thanks for any tips,
Mandar.

Is this a known problem?

Hi,

that's a bug and security risk IMO. It should never happen.

Please report it: M-x report-emacs-bug

Thanks

Hi,

I just used Emacs built-in bug-reporting facility (M-x
report-emacs-bug RET) and among some other information this includes
the lossage, so if passwords are included in the lossage this is
definitely a security bug. I just tried that with Emacs 23.1.1 and I
can't confirm that bug, it looks like the lossage is flushed after the
password prompt finishes.

Hi,

it's not flushed in a similar case with

In GNU Emacs 23.1.92.1 (i686-pc-linux-gnu, GTK+ Version 2.12.0)
 of 2010-02-19

filed a bug report meanwhile:
