Fedora 28: knot-resolver Security Update
Summary
The Knot DNS Resolver is a caching full resolver implementation written in C
and LuaJIT, including both a resolver library and a daemon. Modular
architecture of the library keeps the core tiny and efficient, and provides
a state-machine like API for extensions.
The package is pre-configured as local caching resolver.
To start using it, start a single kresd instance:
$ systemctl start kresd@1.service
Knot Resolver 2.3.0 (2018-04-23) ================================ Security
-------- - fix CVE-2018-1110: denial of service triggered by malformed DNS
messages (!550, !558, security!2, security!4) - increase resilience against
slow lorris attack (security!5) Bugfixes -------- - validation: fix SERVFAIL in
case of CNAME to NXDOMAIN in a single zone (!538) - validation: fix SERVFAIL for
DS . query (!544) - lib/resolve: don't send unecessary queries to parent zone
(!513) - iterate: fix validation for zones where parent and child share NS
(!543) - TLS: improve error handling and documentation (!536, !555, !559)
Improvements ------------ - prefill: new module to periodically import root zone
into cache (replacement for RFC 7706, !511) - network_listen_fd: always create
end point for supervisor supplied file descriptor - use CPPFLAGS build
environment variable if set (!547)
