BIND named DNA datagram denial of service
| bind-named-dns-dos (19062) |  Low Risk |
Description:
BIND (the Berkeley Internet Name Daemon) is vulnerable to a denial of service attack, caused by a vulnerability in the authvalidated function. If DNSSEC validation is enabled, which is not the default setting, a remote attacker could send a specially-crafted DNS datagram to cause the named process to crash.
Consequences:
Denial of Service
Remedy:
Upgrade to the latest version of BIND (9.3,1 or later), available from the Internet Software Consortium (ISC) Web site. See References.
