Security Fixes

    The rules for acceptance of records into the cache have been tightened to prevent the possibility of poisoning if forwarders send records outside the configured bailiwick. (CVE-2021-25220)

    ISC would like to thank Xiang Li, Baojun Liu, and Chaoyi Lu from Network and Information Security Lab, Tsinghua University, and Changgen Zou from Qi An Xin Group Corp. for bringing this vulnerability to our attention. [GL #2950]

    TCP connections with keep-response-order enabled could leave the TCP sockets in the CLOSE_WAIT state when the client did not properly shut down the connection. (CVE-2022-0396) [GL #3112]
