FreeBSD : FreeBSD -- BIND named(8) cache poisoning with DNSSEC validation (e500b9bf-ca3e-11df-aade-0050568f000c)

High Nessus Plugin ID 50337


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


If a client requests DNSSEC records with the Checking Disabled (CD) flag set, BIND may cache the unvalidated responses. These responses may later be returned to another client that has not set the CD flag.


Update the affected packages.
