Name of the Vulnerable Software and Affected Versions Astra Linux (affected versions not specified)

Description The issue is related to errors in the algorithm for recalculating resolution when changing the window size of the built-in screen locker in the fly-wm window manager of Astra Linux. This can lead to the possibility of displaying confidential data in a running virtual machine or in a nested session after the screen is locked inside a guest machine running under Astra Linux. Exploitation of this issue may allow an attacker to access confidential data on the guest machine's desktop by manipulating the screen resolution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
