Tenable has extracted the preceding description block directly from the SUSE 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.0,     distribution can restore read access in repo a after an explicit delete when storage.cache.blobdescriptor:
    redis and storage.delete.enabled: true are both enabled. The delete path clears the shared digest     descriptor but leaves stale repo-scoped membership behind, so a later Stat or Get from repo b repopulates     the shared descriptor and makes the deleted blob readable from repo a again. This vulnerability is fixed     in 3.1.0. (CVE-2026-35172)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 45 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-d7d99f08ff advisory.

    Automatic update for docker-distribution-3.1.1-1.fc45.
