Package : gnome-shell
Version : 3.22.3-3+deb9u1
CVE ID : CVE-2020-17489
Debian Bug : #968311

It was discovered that there was an issue around revealing passwords
in the "gnome-shell" component of the GNOME desktop.

In certain configurations, when logging out of an account the
password box from the login dialog could reappear with the password
visible in cleartext.

For Debian 9 "Stretch", this problem has been fixed in version
3.22.3-3+deb9u1.

We recommend that you upgrade your gnome-shell packages.

For the detailed security status of gnome-shell please refer to
its security tracker page at:
