Moby is an open source container framework. Prior to version 29.3.1, a security vulnerability has been detected that allows plugins privilege validation to be bypassed during docker plugin install. Due to an error in the daemon's privilege comparison logic, the daemon may incorrectly accept a privilege set that differs from the one approved by the user. Plugins that request exactly one privilege are also affected, because no comparison is performed at all. This issue has been patched in version 29.3.1.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1659 advisory.

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. Prior to 1.43.0, the otlp HTTP exporters     (traces/metrics/logs) read the full HTTP response body into an in-memory bytes.Buffer without a size cap.
    This is exploitable for memory exhaustion when the configured collector endpoint is attacker-controlled     (or a network attacker can mitm the exporter connection). This vulnerability is fixed in 1.43.0.

The version of docker installed on the remote host is prior to 25.0.14-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2DOCKER-2026-114 advisory.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-853a2fa7e5 advisory.

    - Update to release v29.4.0
    - Resolves: rhbz#2455894
    - Resolves  CVE-2026-34986: rhbz#2455665
    - Upstream new features and fixes

    ----

    - Update to release v29.3.1
    - Resolves: rhbz#2451425
    - Upstream notes that this release resolves: CVE-2026-34040,       CVE-2026-33997, CVE-2026-33748, CVE-2026-33747
    - Upstream fixes

Tenable has extracted the preceding description block directly from the Fedora 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 the Docker Engine installed on the remote host is prior to 29.3.1. It is therefore affected by multiple vulnerabilities:

  - CVE-2026-34040: AuthZ plugin authorization bypass vulnerability. Authorization plugins could be bypassed     under specific conditions, potentially allowing unauthorized access.

  - CVE-2026-33997: Plugin privilege validation bypass vulnerability in 'docker plugin install' command.
    A flaw in privilege validation could be partially bypassed, potentially leading to unauthorized privilege     escalation.

  - CVE-2026-33748: BuildKit Git URL validation vulnerability. Insufficient validation of Git URL '#ref:subdir'     fragments could allow access to files outside the intended repository scope, leading to unauthorized     information disclosure.

  - CVE-2026-33747: BuildKit arbitrary file write vulnerability. An untrusted frontend could cause files to be     written outside the BuildKit state directory, potentially allowing local privilege escalation or unauthorized     file writes.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
