"Notes for BIND 9.11.28
Security Fixes

When tkey-gssapi-keytab or tkey-gssapi-credential was configured,
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 to use for GSSAPI authentication). This flaw could
be exploited to crash named. Theoretically, it also enabled remote code
execution, but achieving the latter is very difficult in real-world
conditions. (CVE-2020-8625)

This vulnerability was responsibly reported to us as ZDI-CAN-12302
by Trend Micro Zero Day Initiative. [GL #2354]"
