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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-161 advisory.

    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.
    (CVE-2022-2795)

    A flaw was found in the Bind package, where the resolver can crash when stale cache and stale answers are     enabled, option stale-answer-client-timeout is set to 0 and there is a stale CNAME in the cache for an     incoming query. By sending specific queries to the resolver, an attacker can cause named to crash.
    (CVE-2022-3080)

    Sending a flood of dynamic DNS updates may cause `named` to allocate large amounts of memory. This, in     turn, may cause `named` to exit due to a lack of free memory. We are not aware of any cases where this has     been exploited. Memory is allocated prior to the checking of access permissions (ACLs) and is retained     during the processing of a dynamic update from a client whose access credentials are accepted. Memory     allocated to clients that are not permitted to send updates is released immediately upon rejection. The     scope of this vulnerability is limited therefore to trusted clients who are permitted to make dynamic zone     changes. If a dynamic update is REFUSED, memory will be released again very quickly. Therefore it is only     likely to be possible to degrade or stop `named` by sending a flood of unaccepted dynamic updates     comparable in magnitude to a query flood intended to achieve the same detrimental outcome. BIND 9.11 and     earlier branches are also affected, but through exhaustion of internal resources rather than memory     constraints. This may reduce performance but should not be a significant problem for most servers.
    Therefore we don't intend to address this for BIND versions prior to BIND 9.16. This issue affects BIND 9     versions 9.16.0 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.8-S1 through     9.16.36-S1. (CVE-2022-3094)

    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. (CVE-2022-3488)

    A flaw was found in Bind, where a resolver crash is possible. When stale cache and stale answers are     enabled, the option stale-answer-client-timeout is set to a positive integer, and the resolver receives an     RRSIG query. (CVE-2022-3736)

    By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can     trigger a small memory leak. It is possible to gradually erode available memory to the point where named     crashes for lack of resources. (CVE-2022-38177)

    By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can     trigger a small memory leak. It is possible to gradually erode available memory to the point where named     crashes for lack of resources. (CVE-2022-38178)

    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. If there are sufficient clients already waiting when a new client query     is received so that it is necessary to SERVFAIL the longest waiting client (see BIND 9 ARM `recursive-     clients` limit and soft quota), then it is possible for a race to occur between providing a stale answer     to this older client and sending an early timeout SERVFAIL, which may cause an assertion failure. 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. (CVE-2022-3924)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of ISC BIND installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cve-2022-3488 advisory.
