CVE-2016-9778 (GCVE-0-2016-9778)

Vulnerability from cvelistv5 – Published: 2019-01-16 20:00 – Updated: 2024-09-16 20:01

Title

An error handling certain queries using the nxdomain-redirect feature could cause a REQUIRE assertion failure in db.c

Summary

An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes. Please note: This vulnerability affects the "nxdomain-redirect" feature, which is one of two methods of handling NXDOMAIN redirection, and is only available in certain versions of BIND. Redirection using zones of type "redirect" is not affected by this vulnerability. Affects BIND 9.9.8-S1 -> 9.9.8-S3, 9.9.9-S1 -> 9.9.9-S6, 9.11.0-9.11.0-P1.

Severity

7.5 (High)


                        
                          CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE

Only servers which are performing NXDOMAIN redirection using the "nxdomain-redirect" function are potentially vulnerable and then only a subset of those servers. In order to be affected a server must be using nxdomain-redirect AND must be redirecting NXDOMAIN responses for a zone for which the server also provides authoritative service -- therefore a purely recursive server is not at risk, either. Successful exploitation of the vulnerability will cause named to stop execution after encountering a REQUIRE assertion failure in db.c, resulting in denial of service to clients.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
