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.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
