Descriptions
Memory access out of buffer boundaries issues was discovered in Contiki-NG 4.4 through 4.5, in the SNMP BER encoder/decoder. The length of provided input/output buffers is insufficiently verified during the encoding and decoding of data. This may lead to out-of-bounds buffer read or write access in BER decoding and encoding functions.

La longitud de los búferes de entrada/salida proporcionados no son verificados suficientemente durante la codificación y decodificación de datos. Esto puede conllevar a un acceso de lectura o escritura del búfer fuera de límites en las funciones de decodificación y codificación de BER.
