CVE-2023-5517

A flaw in query-handling code can cause named to exit prematurely with an assertion failure when: - nxdomain-redirect ; is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response. This issue affects BIND 9 versio...

CVE-2023-4408

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...

CVE-2023-4408

The CVE-2023-4408 issue is a vulnerability in the DNS message parsing of BIND's named where the parsing path has an overly high computational complexity. A crafted large or malformed DNS message can cause high CPU usage on affected BIND 9 releases, potentially impacting both authoritative servers...
