CVE-2023-37459 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 does not first verify that a full TCP...

CVE-2023-37459

CVE-2023-37459 maps to Contiki-NG ≤ 4.9, where the network stack, on receiving a TCP packet with the SYN flag, may access the TCP header before ensuring it is complete. This can trigger an out-of-bounds read from the packet buffer due to reading the flags field in check_for_tcp_syn. The result is...

CVE-2023-37281

CVE-2023-37281 affects Contiki-NG (versions ≤ 4.9) where IPHC header decompression lacks a bounds check before decoding the IPv6 address. An attacker-controlled value (postcount) can trigger an out-of-bounds read via the line memcpy(&ipaddr->u8[16 - postcount], iphc_ptr, postcount);, enabling ...
