SCA: security update for github.com/moby/go-archive (GHSA-hfg8-hc9c-6c3h)

high Tenable Cloud Security Plugin ID 446091

Description

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

 - The tar extraction routines in moby/go-archive (Unpack, UnpackLayer, Untar/UntarUncompressed, and the
 ApplyLayer helpers) do not confine filesystem operations to the destination directory. The extractor
 decides where each archive entry lands using lexical string checks and then performs the filesystem
 operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of
 the destination directory. An attacker who controls the contents of an archive can create or overwrite
 files at arbitrary paths writable by the extracting process. (CVE-2026-17106)

Solution

Update the github.com/moby/go-archive library and its related packages to version 0.3.0 or later.
