  "details": "Contiki-NG is an open-source, cross-platform operating system for IoT devices. An out-of-bounds read of 1 byte can be triggered when sending a packet to a device running the Contiki-NG operating system with SNMP enabled. The SNMP module is disabled in the default Contiki-NG configuration. The vulnerability exists in the os/net/app-layer/snmp/snmp-ber.c module, where the function snmp_ber_decode_string_len_buffer decodes the string length from a received SNMP packet. In one place, one byte is read from the buffer, without checking that the buffer has another byte available, leading to a possible out-of-bounds read. The problem has been patched in Contiki-NG pull request #2936. It will be included in the next release of Contiki-NG. Users are advised to apply the patch manually or to wait for the next release. A workaround is to disable the SNMP module in the Contiki-NG build configuration.",
