An issue in mz-automation libiec61850 v.1.5.3 and before, allows a remote attacker to cause a denial of service (DoS) via the mmsServer_handleDeleteNamedVariableListRequest function of src/mms/iso_mms/server/mms_named_variable_list_service.c.
A denial of service vulnerability exists in the parseNormalModeParameters functionality of MZ Automation GmbH libiec61850 1.5.0. A specially-crafted series of network requests can lead to denial of service. An attacker can send a sequence of malformed iec61850 messages to trigger this vulnerability.
In the MZ Automation LibIEC61850 in versions prior to 1.5.1 an unauthenticated attacker can craft a goose message, which may result in a denial of service.
A NULL pointer dereference in AcseConnection_parseMessage at src/mms/iso_acse/acse.c of libiec61850 v1.5.0 can lead to a segmentation fault or application crash.
