GLSA-200705-14 : XScreenSaver: Privilege escalation

medium Nessus Plugin ID 25235

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The 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.
 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.

Solution

All XScreenSaver users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=x11-misc/xscreensaver-5.02'
