An out-of-bounds memory corruption vulnerability exists in the way Pixar OpenUSD 20.05 uses SPECS data from binary USD files. A specially crafted malformed file can trigger an out-of-bounds memory access and modification which results in memory corruption. To trigger this vulnerability, the victim needs to access an attacker-provided malformed file.
