Bug 211154 – net-misc/vnc: `vncviewer -passwdInput true` echo the password typed

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Carlo Marcelo Arenas Belon 2008-02-23 06:41:08 UTC]

-passwdInput is added to the realvnc ebuild (at least in version 4.1.2-r3) as part of patch 37_all_vnc-password-stdin.patch, that retrieves the password from stdin (using a 3 line C++ std::cin call).

as a result the password is getting printed as it is typed, while it is expected for passwords that they are entered without echo.

Reproducible: Always

Steps to Reproduce:
1. vncviewer -passwdInput true
2. type password
3.

Actual Results:  
password is echo

Expected Results:  
no echo

a new patch could be applied on top of 37 or patch 37 changed so that STDIN has echo disabled while the password is entered with code like :

#include <termios.h>

termios t;
tcgetattr (STDIN_FILENO, &t);
t.c_lflag &= (~ECHO);
tcsetattr (STDIN_FILENO, TCSANOW, &t);
...
t.c_lflag |= ECHO;
tcsetattr (STDIN_FILENO, TCSANOW, &t);

Submit this to tigervnc's upstream please. net-misc/vnc is dead
