Affected: ISC BIND 9

An attacker who knows (or guesses) that a resolver uses RPZ with wildcard CNAME policies can craft query names long enough to trigger a NAMETOOLONG error condition during RPZ processing. This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an unexpected exit of the BIND 9 software. This issue affects BIND 9 versions 9.16.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.16.8-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.

Affected: Ubuntu:22.04:LTS: bind9, Ubuntu:24.04:LTS: bind9, Ubuntu:26.04:LTS: bind9

It was discovered that Bind incorrectly accepted NSEC3 records whose signer name did not match the owning zone. A remote attacker could possibly use this issue to perform NSEC3 impersonation attacks, bypassing DNSSEC validation. (CVE-2026-10723)

It was discovered that Bind incorrectly handled Key Records using the PRIVATEDNS algorithm. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. (CVE-2026-10822)

It was discovered that Bind incorrectly handled wildcard CNAME expansion in Response Policy Zones. A remote attacker could possibly use this issue to bypass configured RPZ policies. (CVE-2026-11331)

It was discovered that Bind performed unnecessary validation of DNSSEC signed records. A remote attacker could possibly use this issue to cause Bind to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-11605)

It was discovered that Bind incorrectly tracked memory usage in the DNS cache. A remote attacker could possibly use this issue to cause Bind to use memory beyond configured limits, leading to a denial of service. (CVE-2026-11622)

It was discovered that Bind incorrectly handled signed wildcard records with label count discrepancies and RRSIG validation. A remote attacker could possibly use this issue to perform cache poisoning attacks. (CVE-2026-11721)

It was discovered that Bind incorrectly handled certain CNAME and DNAME record orderings in the resolver. A…
