Descriptions

BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period of time, even after the client has terminated the connection.

BIND versiones 9.16.11 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0 y versiones 9.16.11-S1 posteriores a 9.16.26-S1 de BIND Supported Preview Edition. Los flujos TCP específicamente diseñados pueden causar que las conexiones a BIND permanezcan en estado CLOSE_WAIT durante un período de tiempo indefinido, incluso después de que el cliente haya terminado la conexión

A flaw was found in Bind that incorrectly handles certain crafted TCP streams. The vulnerability allows TCP connection slots to be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. This flaw allows a remote attacker to send specially crafted TCP streams with 'keep-response-order' enabled that could cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period, even after the client has terminated the connection. This issue results in BIND consuming resources, leading to a denial of service.
