All supported architectures
gnome-screensaver allows local users to bypass authentication under certain
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:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/gnome-screensaver-2.20.0-r3"
