LIN1021-7236 : Security Advisory - bind - CVE-2023-5517

Created: Feb 18, 2024 Updated: Mar 10, 2024

Resolved Date: Mar 10, 2024

Found In Version: 10.21.20.1

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: Userspace

Description

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.
