Affected Packages

Package Vulnerable Unaffected ------------- ------------ ------------ dev-libs/glib < 2.78.6 >= 2.78.6

Impact

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.

Workaround

There is no known workaround at this time.
