Description Marian Rehak 2019-05-30 07:44:07 UTC 
This issue only affects BIND Supported Preview Edition version 9.10.5-S1 -> 9.11.6-S1! An error in the EDNS Client Subnet (ECS) feature for recursive resolvers can cause BIND to exit with an assertion failure when processing a response that has malformed RRSIGs.
