NVD Description

Note: Versions mentioned in the description apply only to the upstream bind-doc package and not the bind-doc package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

A flaw in query-handling code can cause named to exit prematurely with an assertion failure when:

  • nxdomain-redirect &lt;domain&gt;; 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.
