Researchers publicly disclosed a Knot Resolver RCE flaw and PoC exploit code. The DNS-over-QUIC heap overflow hits 6.3.0; update to 6.4.1 now.

#KnotResolver #DNSoverQUIC #RCE #HeapOverflow #PoC #DNSSecurity
Public Exploit Code Released for Knot Resolver DNS-over-QUIC Remote Code Execution Flaw
TL;DR A researcher published full technical details and working proof-of-concept exploit code for a Knot Resolver RCE bug. The heap out-of-bounds write sits in the DNS-over-QUIC listener and needs no authentication. CZ.NIC shipped the fix a day earlier in version 6.4.1. Why it matters Knot Resolver is CZ.NIC's open-source caching recursive resolver. Large ISPs run it in front of very large subscriber bases.

ISC fixed 9 BIND vulnerabilities in 9.20.26 and 9.21.24. The top BIND vulnerability, CVE-2026-13321, enables DNSSEC cache poisoning. Patch now.

ISC Patches 9 BIND 9 Vulnerabilities, Including a DNSSEC Cache Poisoning Flaw
TL;DR ISC released BIND 9.20.26 and 9.21.24 on July 22, 2026. The updates fix nine flaws in the widely used DNS server. The most serious BIND vulnerability, CVE-2026-13321, enables cross-zone cache poisoning and scores 8.6. Why it matters BIND is one of the most deployed DNS servers on the internet. A cache poisoning flaw there can redirect users to attacker-controlled answers.
