Affected: ISC BIND 9

The DNS message parsing code in `named` includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

Affected: Ubuntu:22.04:LTS: bind9

Shoham Danino, Anat Bremler-Barr, Yehuda Afek, and Yuval Shavitt discovered that Bind incorrectly handled parsing large DNS messages. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-4408)

Elias Heftrig, Haya Schulmann, Niklas Vogel, and Michael Waidner discovered that Bind icorrectly handled validating DNSSEC messages. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-50387)

It was discovered that Bind incorrectly handled preparing an NSEC3 closest encloser proof. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-50868)

It was discovered that Bind incorrectly handled reverse zone queries when nxdomain-redirect is enabled. A remote attacker could possibly use this issue to cause Bind to crash, leading to a denial of service. (CVE-2023-5517)

It was discovered that Bind incorrectly handled recursive resolution when both DNS64 and serve-stable were enabled. A remote attacker could possibly use this issue to cause Bind to crash, leading to a denial of service. (CVE-2023-5679)
