CVE-2020-14937

The CVE-2020-14937 entry concerns Contiki-NG versions 4.4–4.5 where the SNMP BER encoder/decoder mishandles input/output buffer lengths, causing out-of-bounds reads/writes during BER encoding/decoding. Affected component: Contiki-NG SNMP BER encoder/decoder; root cause: insufficient verification ...

CVE-2020-14937

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 ...
