NULL pointer dereference on implicit read of AR specific record index
Impact
P-Net before 1.0.3 has a NULL pointer dereference weakness, allowing a remote unauthenticated attacker to crash the device via an implicit read request without a valid target AR UUID. The affected versions are those less than 1.0.3. This can cause a denial of service.

Verify details against the original sources.P-Net before 1.0.3 dereferences a NULL AR pointer when handling an implicit read request without a valid target AR UUID for a record index that requires an AR (AR specific indices 0xE000-0xEFFF, and the expected identification data of a slot or subslot).
What to do
Upgrade to P-Net 1.0.3 or later.

Original source description
P-Net before 1.0.3 dereferences a NULL AR pointer when handling an implicit read request without a valid target AR UUID for a record index that requires an AR (AR specific indices 0xE000-0xEFFF, and the expected identification data of a slot or subslot). A remote unauthenticated attacker can send such a request to crash the device (denial of service).
