Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200705-14

XScreenSaver incorrectly handles the results of the getpwuid() function
in drivers/lock.c when using directory servers during a network outage.

Impact :

A local user can crash 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.
