Description
Out-of-bounds Read (CWE-125) in BACnet packet parsing (`bacdt_datetime_to_tod`) in Loytec LIP-ME201C, L-INX, L-GATE, L-ROC, L-IOB, L-DALI, L-VIS and L-PAD through 8.4.18 on LINX-A64 allows an unauthenticated remote attacker to crash `linx_a64.exe` and ultimately reboot the device via a malformed BACnet TimeSynchronization or UTC-TimeSynchronization packet with an invalid month value.
