Overview Affected versions of this package are vulnerable to Improper Validation of Array Index via the NGAP message handling process. An attacker can cause the application to panic and potentially crash by sending specially crafted messages with invalid PDU Session IDs. Remediation Upgrade...

Safety Analysis in the NGAC Model

We study the safety problem for the next-generation access control NGAC model. We show that under mild assumptions it is coNP-complete, and under further realistic assumptions we give an algorithm for the safety problem that significantly outperforms naive brute force search. We also show that...
