How to Fix CVE-2022-38072

To remediate this vulnerability, upgrade all affected Admesh dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

admesh fixed: 0.98.5 
pip install admesh>=0.98.5
Verify Direct and Transitive Dependencies

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

pip show admesh

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-38072, inspect your installed packages using pip:

pip show admesh

Analyze the terminal output to locate any version of Admesh in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.98.5), your application is affected.

Note: The pip show admesh command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-118: Incorrect Access of Indexable Resource ('Range Error'), where the product does not restrict or incorrectly restricts operations within the boundaries of a resource that is accessed using an index or pointer, such as memory or files. In Admesh, 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

An improper array index validation vulnerability exists in the stl_fix_normal_directions functionality of ADMesh Master Commit 767a105 and v0.98.4. A specially-crafted stl file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
