A flaw in the networking code handling DNS-over-TLS queries may cause
named to terminate unexpectedly due to an assertion failure. This happens
when internal data structures are incorrectly reused under significant
DNS-over-TLS query load. This issue affects BIND 9 versions 9.18.0 through
9.18.18 and 9.18.11-S1 through 9.18.18-S1.
