VAR-202004-0705
Vulnerability from variot - Updated: 2023-12-18 12:35An issue was discovered in Contiki-NG through 4.3 and Contiki through 3.0. An out of bounds write is present in the data section during 6LoWPAN fragment re-assembly in the face of forged fragment offsets in os/net/ipv6/sicslowpan.c. Contiki-NG and Contiki Is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (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 is a buffer error vulnerability in Contiki-NG 4.3 and earlier and Contiki 3.0 and earlier. The vulnerability stems from the fact that when a network system or product performs an operation on memory, the data boundary is not correctly verified, resulting in an incorrect read and write operation to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow
