AcademySoftwareFoundation.openexr is vulnerable to Heap-based Buffer Overflow
33
Low Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
The exrmetrics tool mishandles subsampled channels when a data window has a positive origin, so row or sample addressing can write past a heap allocation. Running exrmetrics on a crafted subsampled EXR can therefore crash the tool or corrupt heap memory. The fix corrects subsampled positive-origin addressing in exrmetrics.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run the exrmetrics tool on untrusted EXR files with subsampled channels and a nonzero data-window origin.
Background info
AcademySoftwareFoundation.openexr is vulnerable to Heap-based Buffer Overflow in versions 3.3.0 - 3.4.13.
