Priority
Description
In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects
9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker
on the network path for a TSIG-signed request, or operating the server
receiving the TSIG-signed request, could send a truncated response to that
request, triggering an assertion failure, causing the server to exit.
Alternately, an off-path attacker would have to correctly guess when a
TSIG-signed request was sent, along with other characteristics of the
packet and message, and spoof a truncated response to trigger an assertion
failure, causing the server to exit.
