Ericsson
Packet Core Gateway (PCG) versions prior to 1.30 contain an Improper Handling
of Missing Values (CWE-230) vulnerability where an attacker continuously
sending a specially crafted message can cause service degradation. The impact continues as long the attack persists but the system recovers from the crashes when the attack stops.
