<p>
|
|
gnome-screensaver is a screensaver, designed to integrate with the
|
|
Gnome desktop, that can replace xscreensaver.

<description>
|
|
<p>
|
|
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.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All gnome-screensaver users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=gnome-extra/gnome-screensaver-2.20.0-r3"</code>
|
