There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Moby is an open source container framework. In Docker Engine prior to version 29.5.1, Docker Daemon
    versions 28.5.2 and prior, and Moby Daemon prior to version 2.0.0-beta.14, a race condition during docker
    cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path,
    potentially overwriting host files or causing denial of service. This issue has been patched in Docker
    Engine version 29.5.1 and Moby Daemon version 2.0.0-beta.14. (CVE-2026-42306)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1783 advisory.

    The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key     with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during     signature verification. This could be triggered by unauthenticated clients during public key     authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
    (CVE-2026-39829)

    A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking     the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a     resource leak per connection. Unsolicited global responses are now discarded. (CVE-2026-39830)

    The Verify() method for FIDO/U2F security key types (sk-ecdsa-sha2-nistp256@openssh.com, sk-ssh-     ed25519@openssh.com) did not check the User Presence flag. Signatures generated without physical touch     were accepted, allowing unattended use of a hardware security key. To restore the previous behavior,     return a no-touch-required extension in Permissions.Extensions from PublicKeyCallback. (CVE-2026-39831)

    The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint     but never enforced it. The key would sign without any confirmation prompt, with no indication to the     caller that the constraint was not in effect. NewKeyring() now returns an error when unsupported     constraints are requested. (CVE-2026-39833)

    Docker: Race condition in docker cp allows bind mount redirection to host path (CVE-2026-42306)

    Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both     the 'key' and 'key.SignatureKey' are checked for @revoked. (CVE-2026-42508)

    Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any     other type of callback is passed other than public key, then the source-address validation would be     skipped. (CVE-2026-46595)

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 docker installed on the remote host is prior to 25.0.16-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2NITRO-ENCLAVES-2026-108 advisory.

An update of the docker package has been released.

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