Synopsis
========<\/p>\n
A vulnerability has been discovered in GLib, which can lead to privilege
escalation.<\/p>\n
Background
==========<\/p>\n
GLib is a library providing a number of GNOME’s core objects and
functions.<\/p>\n
Affected packages
=================<\/p>\n
Package Vulnerable Unaffected
————- ———— ————
dev-libs\/glib < 2.78.6 >= 2.78.6<\/p>\n
Description
===========<\/p>\n
A vulnerability has been discovered in GLib. Please review the CVE
identifier referenced below for details.<\/p>\n
Impact
======<\/p>\n
When a GDBus-based client subscribes to signals from a trusted system
service such as NetworkManager or logind on a shared computer, other
users of the same computer can send spoofed D-Bus signals that the
GDBus-based client will wrongly interpret as having been sent by the
trusted system service. This could lead to the GDBus-based client
behaving incorrectly, with an application-dependent impact.<\/p>\n
Workaround
==========<\/p>\n
There is no known workaround at this time.<\/p>\n
Resolution
==========<\/p>\n
All GLib users should upgrade to the latest version:<\/p>\n
# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-libs\/glib-2.78.6”<\/p>\n
