    Out-of-bounds read when processing a received IPv6 packet

    Contiki-NG is an operating system for internet-of-things devices. In versions 4.9 and prior, when a packet is received, the Contiki-NG network stack attempts to start the periodic TCP timer if it is a TCP packet with the SYN flag set. But the implementation d…

    Out-of-bounds read during IPHC address decompression

    Contiki-NG is an operating system for internet-of-things devices. In versions 4.9 and prior, when processing the various IPv6 header fields during IPHC header decompression, Contiki-NG confirms the received packet buffer contains enough data as needed for tha…

    Out-of-bounds read and write in BLE L2CAP module

    Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. Versions prior to 4.9 are vulnerable to an Out-of-bounds read. While processing the L2CAP protocol, the Bluetooth Low Energy stack of Contiki-NG needs to map an inc…

    Out-of-bounds read when decompressing UDP header

    Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. The 6LoWPAN implementation in Contiki-NG may cast a UDP header structure at a certain offset in a packet buffer. The code does not check whether the packet buffer i…

    Out-of-bounds read in the uIP buffer module

    Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. The low-power IPv6 network stack of Contiki-NG has a buffer module (os/net/ipv6/uipbuf.c) that processes IPv6 extension headers in incoming data packets. As part of…

    Out-of-bounds read in IPv6 neighbor solicitation in Contiki-NG

    Contiki-NG is an open-source, cross-platform operating system for IoT devices. Because of insufficient validation of IPv6 neighbor discovery options in Contiki-NG, attackers can send neighbor solicitation packets that trigger an out-of-bounds read. The proble…
