| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-06-21 | CVE-2023-2911 | Out-of-bounds Write vulnerability in multiple products If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1. | 7.5 |
| 2023-01-26 | CVE-2022-3924 | Reachable Assertion vulnerability in ISC Bind This issue can affect BIND 9 resolvers with `stale-answer-enable yes;` that also make use of the option `stale-answer-client-timeout`, configured with a value greater than zero. If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clients that are waiting for recursion to complete. | 7.5 |
| 2023-01-26 | CVE-2022-3094 | Use After Free vulnerability in ISC Bind Sending a flood of dynamic DNS updates may cause `named` to allocate large amounts of memory. | 7.5 |
| 2023-01-26 | CVE-2022-3488 | Reachable Assertion vulnerability in ISC Bind Processing of repeated responses to the same query, where both responses contain ECS pseudo-options, but where the first is broken in some way, can cause BIND to exit with an assertion failure. 'Broken' in this context is anything that would cause the resolver to reject the query response, such as a mismatch between query and answer name. This issue affects BIND 9 versions 9.11.4-S1 through 9.11.37-S1 and 9.16.8-S1 through 9.16.36-S1. | 7.5 |
| 2023-01-26 | CVE-2022-3736 | Unspecified vulnerability in ISC Bind BIND 9 resolver can crash when stale cache and stale answers are enabled, option `stale-answer-client-timeout` is set to a positive integer, and the resolver receives an RRSIG query. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1. | 7.5 |
| 2022-09-21 | CVE-2022-2795 | By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. | 5.3 |
| 2022-09-21 | CVE-2022-2881 | Out-of-bounds Read vulnerability in ISC Bind The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process. | 8.2 |
| 2022-09-21 | CVE-2022-2906 | Memory Leak vulnerability in ISC Bind An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. | 7.5 |
| 2022-09-21 | CVE-2022-38177 | Memory Leak vulnerability in multiple products By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. | 7.5 |
| 2022-09-21 | CVE-2022-38178 | Memory Leak vulnerability in multiple products By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. | 7.5 |
