AcademySoftwareFoundation.openexr is vulnerable to Stack-based Buffer Overflow
55
Medium Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
OpenEXR's HTJ2K path accepts JPEG 2000 SIZ image-offset and tile-grid fields where the first tile does not intersect the declared image. A crafted HTJ2K EXR can therefore drive the vendored OpenJPH decoder into invalid tile geometry and a stack buffer overflow during decode. The fix rejects SIZ geometries whose first tile does not intersect the image before decode proceeds.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you decode untrusted HTJ2K-compressed EXR files.
