Austin Hackers Anonymous report:

Due to a failure in validating the number of scanline samples of a OpenEXR file containing deep scanline data, Academy Software Foundation OpenEXR image parsing library version 3.2.1 and prior is susceptible to a heap-based buffer overflow vulnerability.

[…] it is in a routine that is predominantly used for development and
testing. It is not likely to appear in production code.
