Update to version 1.9.12.
- https://www.dnsdist.org/changelog.html#change-1.9.12
Security issues fixed:
- CVE-2026-0396: crafted DNS queries triggering domain-based dynamic rules can lead to HTML injection in the web
dashboard (bsc#1261236).
- CVE-2026-0397: misconfiguration of the CORS policy can lead to information disclosure (bsc#1261237).
- CVE-2026-24028: crafted DNS packet parsed by Lua code using `newDNSPacketOverlay` can lead to an out-of-bounds read
(bsc#1261238).

- CVE-2026-27853: crafted DNS responses sent to a DNSdist using certain methods in custom Lua code (`changeName`) can
lead to an out-of-bounds write (bsc#1261243).
- CVE-2026-27854: crafted DNS queries sent to a DNSdist using the `DNSQuestion:getEDNSOptions` method in custom Lua
code can lead to a use-after-free (bsc#1261241).
