Linux Distros Unpatched Vulnerability : CVE-2026-85747

medium Nessus Plugin ID 365574

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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 3.1.2, registry/client.(*manifests).Get() reads a manifest returned for a digest-pinned request and passes it to distribution.UnmarshalManifest without hashing the body against the requested digest, allowing a malicious or intercepted registry response to substitute attacker-chosen manifest content even when Docker-Content- Digest claims the requested value. The bundled pull-through proxy in registry/proxy/proxymanifeststore.go can cache and re-serve the substituted manifest. This issue is fixed in version 3.1.2. (CVE-2026-85747)

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

Solution

There is no known solution at this time.
