AcademySoftwareFoundation.openexr is vulnerable to Heap-based Buffer Overflow
33
Low Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
The exrmetrics tool computes deep scanline sample-count buffer sizes with 64-bit arithmetic but truncates when resizing vectors on ILP32 builds. A crafted deep scanline EXR with very large dimensions can therefore undersize the sample-count allocation and write past it while exrmetrics reads the file. The fix rejects or correctly sizes the oversized allocation on 32-bit builds.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run the 32-bit (ILP32) exrmetrics tool on untrusted EXR files that exercise deep scanline sample-count table.
Background info
AcademySoftwareFoundation.openexr is vulnerable to Heap-based Buffer Overflow in versions 3.3.0 - 3.4.13.
How to fix this
Upgrade the AcademySoftwareFoundation.openexr library to the patch version.
