CVE-2022-36052 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 is large enough to fit a full UDP heade...

CVE-2022-33989

CVE-2022-33989 concerns dproxy-nexgen (dproxy nexgen), which uses a static UDP source port that is chosen randomly only at boot for upstream DNS queries. The limited entropy enables DNS cache poisoning since traffic injection becomes easier without a fresh, per-query port randomization. Connected...

CVE-2022-34294

The CVE-2022-34294 entry concerns totd 1.5.3, a small DNS proxy nameserver. The issue is that upstream DNS queries use a fixed UDP source port, providing insufficient entropy and enabling DNS cache poisoning. Affected component: totd 1.5.3. Root cause: fixed UDP source port in upstream queries to...
