- A coding error in the
nxdomain-redirectfeature could lead to an assertion failure if the redirection namespace was served from a local authoritative data source such as a local zone or a DLZ instead of via recursive lookup. This flaw is disclosed in CVE-2016-9778. [RT #43837]
- Named could mishandle authority sections that were missing RRSIGs triggering an assertion failure. This flaw is disclosed in CVE-2016-9444. [RT # 43632]
- Named mishandled some responses where covering RRSIG records are returned without the requested data resulting in a assertion failure. This flaw is disclosed in CVE-2016-9147. [RT #43548]
- Named incorrectly tried to cache TKEY records which could trigger a assertion failure when there was a class mismatch. This flaw is disclosed in CVE-2016-9131. [RT #43522]
- It was possible to trigger assertions when processing a response. This flaw is disclosed in CVE-2016-8864. [RT #43465]
