Name of the Vulnerable Software and Affected Versions ISC BIND versions 9.9.9 through 9.9.9-P1 ISC BIND versions 9.10.x through 9.10.4-P1 ISC BIND versions 9.11.x through 9.11.0b1

Description The issue allows primary DNS servers to cause a denial of service (secondary DNS server crash) via a large AXFR response. It also possibly allows IXFR servers to cause a denial of service (IXFR client crash) via a large IXFR response. Additionally, remote authenticated users can cause a denial of service (primary DNS server crash) via a large UPDATE message.

Recommendations For ISC BIND versions 9.9.9 through 9.9.9-P1, update to a version that includes the fix for this issue. For ISC BIND versions 9.10.x through 9.10.4-P1, update to a version that includes the fix for this issue. For ISC BIND versions 9.11.x through 9.11.0b1, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting the size of AXFR and IXFR responses to prevent large responses from causing a denial of service. Restrict access to the UPDATE message functionality to minimize the risk of exploitation by remote authenticated users.
