Vulnerability from cvelistv5 – Published: 2024-02-13 14:04 – Updated: 2025-02-13 17:25

Title

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

Summary

A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: - `nxdomain-redirect <domain>;` 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 versions 9.12.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

UBUNTU-CVE-2023-5517 (CVE-2023-5517)

Vulnerability from osv_ubuntu – Published: 2024-02-13 00:00 – Updated: 2026-04-22 07:45 – Source website

Details

A flaw in query-handling code can cause named to exit prematurely with an assertion failure when: - nxdomain-redirect <domain>; 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 versions 9.12.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

Severity

7.5 (High)
