GLSA-200804-12 : gnome-screensaver: Privilege escalation

This script is Copyright (C) 2008-2017 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200804-12
(gnome-screensaver: Privilege escalation)

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.

Impact :

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.

Workaround :

There is no known workaround at this time.

Solution :

All gnome-screensaver users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=gnome-extra/gnome-screensaver-2.20.0-r3'

Risk factor :

Medium / CVSS Base Score : 4.7
