Details
Kishore Kumar Kothapalli discovered that Bind incorrectly handled the lame
cache when processing responses. A remote attacker could possibly use this
issue to cause Bind to consume resources, resulting in a denial of service.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10

In general, a standard system update will make all the necessary changes.
