XScreenSaver is a widely used screen saver collection shipped on
|
|
systems running the X11 Window System.

<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 ">=x11-misc/xscreensaver-5.02"</code>
|
