Upgrade Ubuntu:22.04 bind9 to version 1:9.18.12-0ubuntu0.22.04.3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream bind9 package and not the bind9 package as distributed by Ubuntu.
See How to fix? for Ubuntu:22.04 relevant fixed versions and status.
The code that processes control channel messages sent to named calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing named to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary.
This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1.
