D-Bus is a daemon providing a framework for applications to communicate with one another. GLib is a library providing a number of GNOMEâ€™s core objects and functions.
When libdbus is used in a setuid program, a user can gain escalated privileges by leveraging the DBUS_SYSTEM_BUS_ADDRESS variable. GLib can be used in a setuid context with D-Bus, and so can trigger this vulnerability. Please review the CVE identifier below for more details.
A local attacker could gain escalated privileges and execute arbitrary code.
There is no known workaround at this time.
All D-Bus users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.6.8"
All GLib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.32.4-r1"
