<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.

</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>

<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-misc/xscreensaver-5.02&quot;</code>
</resolution>
