Summary

A weakness was identified in meshio up to 5.3.5 in an unknown function of meshio/_vtk_42.py within the VTK Reader component. Manipulating the DIMENSIONS argument can lead to uncontrolled memory allocation, and the attack can be executed remotely. The project was informed early via an issue report but has not responded yet.

Risk Assessment

A remote attacker could cause uncontrolled memory allocation, leading to resource exhaustion and denial of service in applications processing VTK files. The risk applies to systems accepting untrusted input files.

Recommendation

Restrict processing of untrusted VTK files through meshio and monitor memory usage. Track the meshio project for fix availability.
