Mandriva Linux Security Advisory 2013-083 - It was discovered that the version of glib shipped with MBS 1 does not sanitise certain DBUS related environment variables. When used in combination with a setuid application which utilizes dbus via glib, a local user could gain escalated privileges with a specially crafted environment. This is related to a similar issue with dbus. This updated version of glib adds appropriate protection against such scenarios and also adds additional hardening when used in a setuid environment.

Package : glib2.0
Date : April 9, 2013
Affected: Business Server 1.0

Problem Description:

Updated glib2.0 packages fix security vulnerability:

It was discovered that the version of glib shipped with MBS 1 does
not sanitise certain DBUS related environment variables. When used
in combination with a setuid application which utilises dbus via
glib, a local user could gain escalated privileges with a specially
crafted environment. This is related to a similar issue with dbus
(CVE-2012-3524).

This updated version of glib adds appropriate protection against
such scenarios and also adds additional hardening when used in a
setuid environment.
