OpenEXR is vulnerable to Information Disclosure
33
Low Risk
This Affects:
OpenEXRTL;DR
OpenEXR reconstructs pixel channels from an under-filled decode buffer for certain compressed EXR chunks in the Core path embedded in the PyPI OpenEXR module, so uninitialized resource bytes can be copied into caller-visible output. A crafted EXR decoded through the Python bindings can therefore disclose stale process memory via pixel data. 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 EXR files through the OpenEXR Python bindings.
Background info
OpenEXR is vulnerable to Information Disclosure in versions 3.2.3 - 3.4.13.
How to fix this
Upgrade the OpenEXR library to the patch version.
