ISC reports:
A query with a specific set of characteristics could
cause a server using DNS64 to encounter an assertion
failure and terminate.
An attacker could deliberately construct a query,
enabling denial-of-service against a server if it
was configured to use the DNS64 feature and other
preconditions were met.
Mistaken assumptions about the ordering of records in
the answer section of a response containing CNAME or
DNAME resource records could lead to a situation in
which named would exit with an assertion failure when
processing a response in which records occurred in an
unusual order.
named contains a feature which allows operators to
issue commands to a running server by communicating
with the server process over a control channel,
using a utility program such as rndc.
A regression introduced in a recent feature change
has created a situation under which some versions of
named can be caused to exit with a REQUIRE assertion
failure if they are sent a null command string.
