Buffer overflow

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. Functions parsing the OIDs in SNMP requests lack sufficient allocated target-buffer capacity verification when writing parsed OID values. The function snmpoiddecodeoid may overwrite memory areas beyond the provided...

CVE-2020-14936

CVE-2020-14936 concerns Contiki-NG 4.4–4.5, where the SNMP agent contains a buffer overflow in snmp_oid_decode_oid() triggered during SNMP request processing. The function does not sufficiently validate target-buffer capacity when writing parsed OID values, risking overwriting memory beyond the i...

CVE-2020-14936: Out-of-bounds Write

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. Functions parsing the OIDs in SNMP requests lack sufficient allocated target-buffer capacity verification when writing parsed OID values. The function snmpoiddecodeoid may overwrite memory areas beyond the provided...
