AcademySoftwareFoundation.openexr is vulnerable to Information Disclosure
33
Low Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
OpenEXRCore's NO_COMPRESSION scanline path accepts a chunk shorter than the declared unpacked pixel data. The short chunk leaves part of the destination buffer uninitialized, and those bytes can be copied into caller-visible pixels during decode. 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 scanline EXR files.
Background info
