According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: -     `nxdomain-redirect domain;` is configured, and - the resolver receives a PTR query for an RFC 1918     address that would normally result in an authoritative NXDOMAIN response.(CVE-2023-5517)

    A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure     during recursive resolution, when both of these features are enabled.This issue affects BIND 9 versions     9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through 9.16.45-S1,     and 9.18.11-S1 through 9.18.21-S1.(CVE-2023-5679)

    To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to     clean up the database. It uses several methods, including some that are asynchronous: a small chunk of     memory pointing to the cache element that can be cleaned up is first allocated and then queued for later     processing. It was discovered that if the resolver is continuously processing query patterns triggering     this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely     manner. This in turn enables the list of queued cleanup events to grow infinitely large over time,     allowing the configured `max-cache-size` limit to be significantly exceeded.(CVE-2023-6516)

Tenable has extracted the preceding description block directly from the EulerOS bind 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 remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:2551 advisory.

  - 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-2023-4408)

  - 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-2023-50387)

  - 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. (CVE-2023-50868)

  - A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: -     `nxdomain-redirect <domain>;` is configured, and - the resolver receives a PTR query for an RFC 1918     address that would normally result in an authoritative NXDOMAIN response.
