CVE-2020-6155

A heap overflow vulnerability exists in the Pixar OpenUSD 20.05 while parsing compressed value rep arrays in binary USD files. A specially crafted malformed file can trigger a heap overflow, which can result in remote code execution. To trigger this vulnerability, the victim needs to access an attacker-provided malformed file.
