Type: security
Affected Mageia releases: 7
CVE: CVE-2018-5743,
     CVE-2019-6471

Updated bind packages fix security vulnerabilities

Limiting simultaneous TCP clients is ineffective (CVE-2018-5743)

Race condition when discarding malformed packets can cause bind to
exit with assertion failure (CVE-2019-6471)

In addition to those two security issues, this package releases also
fixes two additional issues:
- a missing conflict tag between old bind and bnew ind-utils subpackages,
  preventing upgrade due to a file conflict
- missing root.key file, despite this one being refered in default
  configuration
