CVE-2012-1620
First published: Wed Feb 01 2012(Updated: )
<a href="https://bugs.gentoo.org/show_bug.cgi?id=401645">https://bugs.gentoo.org/show_bug.cgi?id=401645</a> Jeroen Roovers 2012-01-31 17:23:28 UTC 1) In a terminal, I run `slock & sleep 5; <some X app>' 2) After about 10 seconds, I press some keys that slock would interpret as a password. 3a) It does not allow me to use <some X app> - all keyboard controls are captured. 3b) Pointer device input is blocked - <some X app> cannot be controlled through the mouse. 4) Entering the correct password unlocks the screen and makes <some X app> focused and in the foreground. The only harm I see here is a possible unwanted disclosure of the information that <some X app> happens to display at the time, but it's a vulnerability sure enough.
