+ <description>
+ <p>
+ XScreenSaver incorrectly handles the results of the getpwuid() function
+ in drivers/lock.c when using directory servers during a network outage.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All XScreenSaver users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=x11-misc/xscreensaver-5.02"</code>
