  • CVSS V3 rated as High - 6.5 severity.
  • CVSS V2 rated as Medium - 4 severity.
    • Solution
    The vendor has released any patch, for more information please visit: K11426315Workaround:
    If incremental zone transfers (IXFR) are enabled in your BIND configuration, you can mitigate this vulnerability by setting the request-ixfr no; option in the desired configuration block (options, zone, or server). Doing so disables incremental zone transfers and prevents the failing assertion from being evaluated.
