 Security Fixes

+- Fixed an assertion failure that occurred in ``named`` when it
+  attempted to send a UDP packet that exceeded the MTU size, if
+  Response Rate Limiting (RRL) was enabled. (CVE-2021-25218) :gl:`#2856`
+
 - ``named`` failed to check the opcode of responses when performing zone
   refreshes, stub zone updates, and UPDATE forwarding. This could lead
   to an assertion failure under certain conditions and has been
   addressed by rejecting responses whose opcode does not match the
   expected value. :gl:`#2762`
