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

medium Nessus Plugin ID 56857

Synopsis

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

Description

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.

Solution

Update the affected packages.
