FreeBSD : FreeBSD -- Incorrect handling of zero-length RDATA fields in named(8) (fc5231b6-c066-11e1-b5e0-000c299b62e1)

high Nessus Plugin ID 59749

Synopsis

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

Description

Problem description :

The named(8) server does not properly handle DNS resource records where the RDATA field is zero length, which may cause various issues for the servers handling them.

Resolving servers may crash or disclose some portion of memory to the client. Authoritative servers may crash on restart after transferring a zone containing records with zero-length RDATA fields. These would result in a denial of service, or leak of sensitive information.

Solution

Update the affected packages.
