Following the v3.1.5 release of OpenEXR, issues were identified in its source
by OSS Fuzz. They have since been addressed in the development branch but
there has not yet been an official release of OpenEXR that incorporates the
fixes.
To include those fixes in the meantime, we apply a patch to the OpenEXR source
used to build the library for the engine:
openexr_v3.1.5_PR_1268_OSS_Fuzz.patch
See the OpenEXR pull request for more detail:
