"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0094 advisory.

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

    CVE-2023-4408:
    The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive
    CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative
    servers and recursive resolvers.
    This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19,
    9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

    CVE-2023-50387:
    Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote
    attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the
    KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the
    protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG
    records.

    CVE-2023-50868:
    The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)
    allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC
    responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an
    algorithm must perform thousands of iterations of a hash function in certain situations.

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