New Debian bind9 1:9.10.3.dfsg.P4-12.3+deb9u9A~4.4.8.202105100950 fixes:
This update addresses the following issues:
* A broken inbound incremental zone update (IXFR) can cause named to  terminate unexpectedly (CVE-2021-25214)
* An assertion check can fail while answering queries for DNAME records that  require the DNAME to be processed to resolve itself (CVE-2021-25215)
* Vulnerability in BIND's GSSAPI security policy negotiation can be targeted  by a buffer overflow attack (CVE-2021-25216)
