CVE-2023-5517 Querying RFC 1918 reverse zones may cause an assertion failure when "nxdomain-redirect" is enabled

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-2023-5517

CVE-2023-5517 is a BIND vulnerability where a flaw in query-handling can cause named to exit with an assertion failure when nxdomain-redirect is configured and a PTR query for an RFC 1918 address would yield NXDOMAIN. Affected: BIND 9.x (various 9.12.0–9.19.19 and related 9.16/9.18 ranges; versio...
