GLSA-200705-14 : XScreenSaver: Privilege escalation
Medium Nessus Plugin ID 25235
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200705-14 (XScreenSaver: Privilege escalation)
XScreenSaver incorrectly handles the results of the getpwuid() function in drivers/lock.c when using directory servers during a network outage.
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.
There is no known workaround at this time.
SolutionAll XScreenSaver users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=x11-misc/xscreensaver-5.02'
