+ When a server's configuration set the
+ <command>tkey-gssapi-keytab</command> or
+ <command>tkey-gssapi-credential</command> 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
+ <command>named</command> binaries compiled for 64-bit platforms, and
+ could enable remote code execution when <command>named</command> was
+ compiled for 32-bit platforms. (CVE-2021-25216)
