GHSA-58p5-r2f6-g2cj: Pixar OpenUSD Sdf_PathNode Module Use-After-Free Vulnerability Leading to Potential Remote Code Execution

Summary

A Use-After-Free (UAF) vulnerability has been discovered in the Sdf_PathNode module of the Pixar OpenUSD library. This issue occurs during the deletion of the Sdf_PrimPathNode object in multi-threaded environments, where freed memory is accessed. This results in segmentation faults or bus errors, allowing attackers to potentially exploit the vulnerability for remote code execution (RCE). By using a specially crafted .usd file, an attacker could gain control of the affected system. The vulnerability has been confirmed in multiple OpenUSD tools, including sdfdump, usdtree, usdcat, and sdffilter.

Patches

This is fixed with commit 0d74f31, with the fix available in OpenUSD 25.08 and onwards.

Details

The issue is a Use-After-Free vulnerability in the Sdf_PathNode destruction process, specifically in Sdf_PrimPathNode::~Sdf_PrimPathNode(). When multiple threads attempt to destroy or modify the same Sdf_PathNode object, a race condition can occur, causing the object to be accessed after it has been freed. This leads to segmentation faults or bus errors, as observed in the crash logs.
