    Критический · CVSS 9.2EPSS 0,43%Публичный эксплойтНет опубликованного исправления

    open62541 1.5.0 before 1.5.7 Integer Overflow Heap Buffer Overflow via Custom DataType

    open62541 1.5.0 before 1.5.7 contains an integer overflow in UA_DataType_fromStructureDescription() that wraps the 16-bit memSize field for large custom structure definitions. A malicious OPC UA server can supply DataType definitions via UA_Client_getRemoteDataTypes(), causing decodeBinaryStructure() to overflow the heap, crashing clients or enabling code execution.
