"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2023:0083 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    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.

    CVE-2022-38177:
    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-2022-38178:
    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-2023-2828:
    Every `named` instance configured to run as a recursive resolver maintains a cache database holding the
    responses to the queries it has recently sent to authoritative servers. The size limit for that cache
    database can be configured using the `max-cache-size` statement in the configuration file; it defaults to
    90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the
    configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets
    from the cache, to keep memory use below the configured limit. It has been discovered that the
    effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the
    resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`
    limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0
    through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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