AcademySoftwareFoundation.openexr is vulnerable to Out-of-bounds Read
70
High Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
On ILP32 builds, OpenEXRCore RLE decode multiplies or accumulates attacker-controlled dimension and sample fields with 32-bit arithmetic before allocating decode buffers. A crafted RLE-compressed EXR can overflow those size computations, produce an undersized buffer, and trigger a heap out-of-bounds read and denial of service. Typical 64-bit builds are not affected. The fix rejects oversized size computations before allocation.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run a 32-bit (ILP32) build that decodes untrusted RLE-compressed EXR files.
Background info
AcademySoftwareFoundation.openexr is vulnerable to Out-of-bounds Read in versions 3.3.0 - 3.3.12 and 3.4.0 - 3.4.13.
How to fix this
