Description Dhananjay Arunesh 2019-01-17 13:08:13 UTC

Mate-screensaver before 1.20.2 in MATE Desktop Environment allows physically
proximate attackers to view screen content and possibly control applications. By
unplugging and re-plugging or power-cycling external output devices (such as
additionally attached graphical outputs via HDMI, VGA, DVI, etc.) the content of
a screensaver-locked session can be revealed. In some scenarios, the attacker
can execute applications, such as by clicking with a mouse.
