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" References ========== [ 1 ] CVE-2007-1859 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1859 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200705-14.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
