CVE-2020-25111

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-2020-17440

An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that parses incoming DNS packets does not validate that domain names present in the DNS responses have '\0' termination. This results in errors when calculating the offset of the pointer that jumps over domain...

CVE-2020-17439

An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that parses incoming DNS packets does not validate that the incoming DNS replies match outgoing DNS queries in newdata in resolv.c. Also, arbitrary DNS replies are parsed if there was any outgoing DNS query wi...

Code injection

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 crafti...

CVE-2020-24341

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing function in picotcp.c does not validate the length of incoming TCP packets, which leads to an out-of-bounds read when assembling received packets into a data segment, eventually causing Denial-of-Servic...

CVE-2020-17437

An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. When the Urgent flag is set in a TCP packet, and the stack is configured to ignore the urgent data, the stack attempts to use the value of the Urgent pointer bytes to separate the Urgent data from the normal data, by...
