Synopsis

The remote name server is affected by a memory exhaustion vulnerability

Description

According to its self-reported version number, the installation of ISC BIND running on the remote name server is affected by a memory exhaustion vulnerability. A server is potentially vulnerable if it accepts zone data from another source, as no limit is currently placed on zone data size.
