How to: CVE-2025-40775 (2025-05-21)
```
When an incoming DNS protocol message includes a Transaction Signature (TSIG), BIND always checks it.  If the TSIG contains an invalid value in the algorithm field, BIND immediately aborts with an assertion failure.\nThis issue affects BIND 9 versions 9.20.0 through 9.20.8 and 9.21.0 through 9.21.7.
