| 2020-08-21 | CVE-2020-8621 | Reachable Assertion vulnerability in multiple products In BIND 9.14.0 -> 9.16.5, 9.17.0 -> 9.17.3, If a server is configured with both QNAME minimization and 'forward first' then an attacker who can send queries to it may be able to trigger the condition that will cause the server to crash. | 4.3 |
| 2020-08-21 | CVE-2020-8620 | Reachable Assertion vulnerability in multiple products In BIND 9.15.6 -> 9.16.5, 9.17.0 -> 9.17.3, An attacker who can establish a TCP connection with the server and send data on that connection can exploit this to trigger the assertion failure, causing the server to exit. | 5.0 |
| 2020-06-17 | CVE-2020-8619 | Improper Resource Shutdown or Release vulnerability in multiple products In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. | 4.9 |
| 2020-06-17 | CVE-2020-8618 | Reachable Assertion vulnerability in multiple products An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients. | 4.9 |
| 2020-05-19 | CVE-2020-8617 | Reachable Assertion vulnerability in multiple products Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. | 5.9 |
| 2019-11-01 | CVE-2019-6470 | There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. | 5.0 |
| 2019-10-16 | CVE-2019-6474 | Missing Release of Resource after Effective Lifetime vulnerability in ISC KEA 1.4.0/1.5.0/1.6.0 A missing check on incoming client requests can be exploited to cause a situation where the Kea server's lease storage contains leases which are rejected as invalid when the server tries to load leases from storage on restart. | 6.1 |
| 2019-10-09 | CVE-2019-6471 | Reachable Assertion vulnerability in multiple products A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. | 5.9 |

| 2019-10-09 | CVE-2019-6467 | Reachable Assertion vulnerability in ISC Bind A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. | 5.0 |
