AcademySoftwareFoundation.openexr is vulnerable to Information Disclosure
33
Low Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
OpenEXRCore's deep NO_COMPRESSION scanline path accepts a chunk whose sample payload is shorter than required for the declared deep samples. The short sample data leaves part of the decode buffer uninitialized, and those bytes can be exposed through decoded deep sample output. The fix rejects undersized compressed or raw streams before reconstructing full channel rows.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you decode untrusted uncompressed deep-scanline EXR files.
