CVE-2019-6467 (GCVE-0-2019-6467)

Vulnerability from cvelistv5 – Published: 2019-10-09 14:17 – Updated: 2024-09-17 00:11
VLAI?
Summary
A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. The most likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the root zone, although other configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4, 9.14.0. Also affects all releases in the 9.13 development branch.
Severity ?
5.9 (Medium)
CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE
  • An attacker who can deliberately trigger the condition on a server with a vulnerable configuration can cause BIND to exit, denying service to other clients.
