| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 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 | Unspecified 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. | 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. | 7.5 |
| 2022-10-07 | CVE-2022-2928 | NULL Pointer Dereference vulnerability in multiple products In ISC DHCP 4.4.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1, when the function option_code_hash_lookup() is called from add_option(), it increases the option's refcount field. | 6.5 |
| 2022-10-07 | CVE-2022-2929 | Allocation of Resources Without Limits or Throttling vulnerability in multiple products In ISC DHCP 1.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1 a system with access to a DHCP server, sending DHCP packets crafted to include fqdn labels longer than 63 bytes, could eventually cause the server to run out of memory. | 6.5 |
| 2022-09-21 | CVE-2022-2795 | Resource Exhaustion vulnerability in multiple products 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 | Improper Verification of Cryptographic Signature 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 |
