SCA: security update for github.com/moby/moby/v2 (GHSA-x86f-5xw2-fm2r)

high Tenable Cloud Security Plugin ID 442038

Description

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

 - Moby is an open source container framework. In versions prior to 29.5.1 and in moby/moby v2 prior to
 v2.0.0-beta.14, when a compressed archive is uploaded to a container via `PUT /containers/{id}/archive` or
 piped through `docker cp -`, the daemon resolves decompression binaries (such as `xz` or `unpigz`) from
 the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious
 container image containing a trojanized decompression binary can achieve arbitrary code execution with
 full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a
 compressed (xz or gzip) archive into that container. This issue is fixed in Docker Engine 29.5.1 and
 moby/moby v2.0.0-beta.14. Workarounds include only running containers from trusted images, using
 authorization plugins to restrict access to the `PUT /containers/{id}/archive` endpoint, and avoiding
 piping compressed archives into containers created from untrusted images (CVE-2026-41567)

Solution

Update the github.com/moby/moby/v2 library and its related packages to version 2.0.0-beta.14 or later.
