https://nvd.nist.gov/vuln/detail/CVE-2020-13495
https://talosintelligence.com/vulnerability_reports/TALOS-2020-1104

Steps to Reproduce

An exploitable vulnerability exists in the way Pixar OpenUSD 20.05 handles file offsets in binary USD files. A specially crafted malformed file can trigger an arbitrary out-of-bounds memory access that could lead to the disclosure of sensitive information. This vulnerability could be used to bypass mitigations and aid additional exploitation. To trigger this vulnerability, the victim needs to access an attacker-provided file.

This problem was fixed in version 20.11, but this CVE was somehow left out of the CHANGELOG. I'll update it, thanks!
