CVE-2021-21280

Contiki-NG is an open-source, cross-platform operating system for internet of things devices. It is possible to cause an out-of-bounds write in versions of Contiki-NG prior to 4.6 when transmitting a 6LoWPAN packet with a chain of extension headers. Unfortunately, the written header is not checke...

Contiki-NG buffer error vulnerability

"Contiki-NG is an open source cross-platform operating system for next-generation IoT devices. An out-of-bounds write vulnerability exists in Contiki-NG versions prior to 4.6 when processing 6LoWPAN extension headers. The vulnerability stems from a failure to check whether the written header is...

CVE-2021-28362

An issue was discovered in Contiki through 3.0. When sending an ICMPv6 error message because of invalid extension header options in an incoming IPv6 packet, there is an attempt to remove the RPL extension headers. Because the packet length and the extension header length are unchecked with respec...

CVE-2020-17442

An issue was discovered in picoTCP 1.7.0. The code for parsing the hop-by-hop IPv6 extension headers does not validate the bounds of the extension header length value, which may result in Integer Wraparound. Therefore, a crafted extension header length value may cause Denial-of-Service because it...

CVE-2020-17468

An issue was discovered in FNET through 4.6.4. The code for processing the hop-by-hop header in the IPv6 extension headers doesn't check for a valid length of an extension header, and therefore an out-of-bounds read can occur in fnetip6extheaderhandleroptions in fnetip6.c, leading to...

Buffer overflow

An issue was discovered in picoTCP 1.7.0. The routine for processing the next header field and deducing whether the IPv6 extension headers are valid doesn't check whether the header extension length field would overflow. Therefore, if it wraps around to zero, iterating through the extension heade...
