| 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-2020-25111 | 1 Contiki-os | 1 Contiki-os | 2020-12-15 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in the IPv6 stack in Contiki through 3.0. There is an insufficient check for the IPv6 header length. This leads to Denial-of-Service and potential Remote Code Execution via a crafted ICMPv6 echo packet. | |||||
| CVE-2020-25112 | 1 Contiki-os | 1 Contiki-os | 2020-12-14 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in the IPv6 stack in Contiki through 3.0. There are inconsistent checks for IPv6 header extension lengths. This leads to Denial-of-Service and potential Remote Code Execution via a crafted ICMPv6 echo packet. | |||||
| 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. | |||||
