Vulnerability from variot
An issue was discovered in Contiki-NG through 4.3 and Contiki through 3.0. A buffer overflow is present due to an integer underflow during 6LoWPAN fragment processing in the face of truncated fragments in os/net/ipv6/sicslowpan.c. This results in accesses of unmapped memory, crashing the application. An attacker can cause a denial-of-service via a crafted 6LoWPAN frame. Contiki-NG and Contiki Exists in an integer overflow vulnerability.Service operation interruption (DoS) It may be put into a state. Contiki is an open source cross-platform operating system for IoT (Internet of Things) devices. Contiki-NG is an open source cross-platform operating system for next-generation IoT (Internet of Things) devices. There are security vulnerabilities in Contiki-NG 4.3 and earlier and Contiki 3.0 and earlier. An attacker could use this vulnerability to cause an application to crash, leading to denial of service
