Synopsis ========
XScreenSaver allows local users to bypass authentication under certain configurations.
Background ==========
XScreenSaver is a widely used screen saver collection shipped on systems running the X11 Window System.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-misc/xscreensaver < 5.02 >= 5.02
Description ===========
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All XScreenSaver users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-misc/xscreensaver-5.02"
