Description Adam Mariš 2016-11-02 15:35:37 UTC

Gnome GDM 3.14.2 and possibly later are vulnerable to an information disclosure vulnerability, specifically when a laptop screen is closed to trigger the screen lock, and the lid is then re-opened the previous contents of the screen are visible for approx. 1 second, which is long enough to take a picture or video record it before the lock screen kicks in.

Why WONTFIX?

(In reply to Tim Jackson from comment #1)
> Why WONTFIX?

Requirement for physical access of the attacker and limited information disclosure as the only impact makes this a Low impact bug, hence WONTFIX.
