CWE-287  (opens in a new tab)

How to fix?

Upgrade bind to version 9.6.1 or higher.

Overview

Affected versions of this package are vulnerable to Improper Authentication. Internet Systems Consortium (ISC) BIND 9.6.0 and earlier does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077 and CVE-2009-0025.
