OpenEXR is vulnerable to Denial of Service
55
Medium Risk
This Affects:
OpenEXRTL;DR
A signed integer overflow while decoding deep tile chunks inside the embedded OpenEXR library can produce an out-of-bounds access and crash a Python process that opens a crafted deep tiled EXR. The fix validates deep-tile size computations with wider arithmetic before indexing.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you decode untrusted deep tiled EXR files through the OpenEXR Python bindings.
Background info
OpenEXR is vulnerable to Denial of Service in versions 3.3.0 - 3.3.12 and 3.4.0 - 3.4.13.
How to fix this
Upgrade the OpenEXR library to the patch version.
