"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]

Feature Changes

DEBUG(1)-level messages were added when starting and ending the BIND 9 task-exclusive mode that stops normal DNS operation (e.g. for reconfiguration, interface scans, and other events that require exclusive access to a shared resource). [GL #3137]

Bug Fixes

The max-transfer-time-out and max-transfer-idle-out options were not implemented when the BIND 9 networking stack was refactored in 9.16. The missing functionality has been re-implemented and outgoing zone transfers now time out properly when not progressing. [GL #1897]

TCP connections could hang indefinitely if the other party did not read sent data, causing the TCP write buffers to fill. This has been fixed by adding a “write” timer. Connections that are hung while writing now time out after the tcp-idle-timeout period has elapsed. [GL #3132]

The statistics counter representing the current number of clients awaiting recursive resolution results (RecursClients) could be miscalculated in certain resolution scenarios, potentially causing the value of the counter to drop below zero. This has been fixed. [GL #3147]"
