gnome-screensaver allows local users to bypass authentication under certain configurations.
gnome-screensaver is a screensaver, designed to integrate with the Gnome desktop, that can replace xscreensaver.
gnome-screensaver incorrectly handles the results of the getpwuid() function in the file src/setuid.c when using directory servers (like NIS) during a network outage, a similar issue to GLSA 200705-14.
A local user can crash gnome-xscreensaver by preventing network connectivity if the system uses a remote directory service for credentials such as NIS or LDAP, which will unlock the screen.
There is no known workaround at this time.
All gnome-screensaver users should upgrade to the latest version:
