CVE-2020-17438 2 Contiki-os, Uip Project 2 Contiki, Uip 2020-12-15 7.5 HIGH 9.8 CRITICAL
An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that reassembles fragmented packets fails to properly validate the total length of an incoming packet specified in its IP header, as well as the fragmentation offset value specified in the IP header. By crafting a packet with specific values of the IP header length and the fragmentation offset, attackers can write into the .bss section of the program (past the statically allocated buffer that is used for storing the fragmented data) and cause a denial of service in uip_reass() in uip.c, or possibly execute arbitrary code on some target architectures.
CVE-2020-24336 2 Contiki-ng, Contiki-os 2 Contiki-ng, Contiki 2020-12-15 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Contiki through 3.0 and Contiki-NG through 4.5. The code for parsing Type A domain name answers in ip64-dns64.c doesn't verify whether the address in the answer's length is sane. Therefore, when copying an address of an arbitrary length, a buffer overflow can occur. This bug can be exploited whenever NAT64 is enabled.
CVE-2019-8359 2 Contiki-ng, Contiki-os 2 Contiki-ng, Contiki 2020-05-01 7.5 HIGH 9.8 CRITICAL
An 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.
