A vulnerability has been identified in D-Bus, which could be exploited by attackers to bypass security restrictions. This issue is caused by errors in the "bus_client_policy_check_can_send()" and "bus_client_policy_check_can_receive()" [bus/policy.c] functions when verifying whether or not a caller is allowed to access a method call, which could be exploited by malicious users with the ability to connect to a vulnerable daemon to execute certain method calls they should normally not have permission to access.
