 > - named crashed when a DNAME record placed in the ANSWER section during
 >   DNAME chasing turned out to be the final answer to a client query.
 >   (CVE-2021-25215)

 > - When a server's configuration set the tkey-gssapi-keytab or
 >   tkey-gssapi-credential option, a specially crafted GSS-TSIG query could
 >   cause a buffer overflow in the ISC implementation of SPNEGO (a protocol
 >   enabling negotiation of the security mechanism used for GSSAPI
 >   authentication).  This flaw could be exploited to crash named binaries
 >   compiled for 64-bit platforms, and could enable remote code execution when
 >   named was compiled for 32-bit platforms.  (CVE-2021-25216)
