Upgrade archive-tar-minitar to 0.5.2
minitar fixed: 0.6 
Upgrade minitar to 0.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for archive-tar-minitar

How to Check if You Are Affected

To determine whether your application is affected by CVE-2016-10173, inspect your project dependencies for Archive tar minitar:

inspect dependencies for archive-tar-minitar

Analyze the terminal output to locate any version of Archive tar minitar in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Archive tar minitar, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Directory traversal vulnerability in the minitar before 0.6 and archive-tar-minitar 0.5.2 gems for Ruby allows remote attackers to write to arbitrary files via a `..` (dot dot) in a TAR archive entry.
