(RHSA-2019:3552) Low: bind security and bug fix update

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es):

• bind: An assertion failure if a trust anchor rolls over to an unsupported key algorithm when using managed-keys (CVE-2018-5745)

• bind: Controls for zone transfers may not be properly applied to DLZs if the zones are writable (CVE-2019-6465)
