Security incidents tagged DNS. Newest first.
ISC disclosed a remotely exploitable memory-corruption bug in BIND 9's named on Oct 21. An attacker who captures a GSS-TSIG signed UDP message (the Kerberos signing used for Active Directory-style dynamic DNS updates) can replay it while the negotiated key is still valid and, combined with crafted queries to a zone they control, may get remote code execution, or at least crash named. CVSS 8.1 (High). No workaround. Affects BIND 9.11.0 through 9.18.50, 9.20.0 through 9.20.29 and 9.21.0 through 9.21.26. Fixed in 9.20.30 and 9.21.27; ISC lists no 9.18 fix. ISC knows of no active exploitation. Debian trixie has a fixed package; Debian bookworm and Ubuntu are still waiting.

Palo Alto Networks PAN-OS Patched
Palo Alto Networks PAN-OS contains a vulnerability in parsing and logging malicious DNS packets in the DNS Security feature that, when exploited, allows an unauthenticated attacker to remotely reboot the firewall. Repeated attempts to trigger this condition will cause the firewall to enter maintenance mode. Added to the CISA KEV catalog on 2024-12-30.
BIND 9 DNS: replaying GSS-TSIG signed UDP messages can corrupt memory in named. Worst case: remote code execution. CVSS 8.1, no workaround. No known exploits yet. Upgrade to 9.20.30 / 9.21.27. On 9.18? Check with ISC. t.co/s2ChkYWdYG
