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

medium Nessus Plugin ID 31959

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-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'
