FreeBSD : BIND -- Remote DOS (90cc1494-10ac-11e1-b3ec-0024e830109b)

medium Nessus Plugin ID 56857
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote FreeBSD host is missing one or more security-related updates.


The Internet Systems Consortium reports :

Organizations across the Internet reported crashes interrupting service on BIND 9 nameservers performing recursive queries. Affected servers crashed after logging an error in query.c with the following message: 'INSIST(! dns_rdataset_isassociated(sigrdataset))' Multiple versions were reported being affected, including all currently supported release versions of ISC BIND 9.

Because it may be possible to trigger this bug even on networks that do not allow untrusted users to access the recursive name servers (perhaps via specially crafted e-mail messages, and/or malicious web sites) it is recommended that ALL operators of recursive name servers upgrade immediately.


Update the affected packages.
