CVE-2024-31047Public exploit

Conversion denial of service via integer overflow

Published Apr 8, 2024 · Updated Aug 2, 2024

Integer overflow in OpenEXR 3.2.3 and earlier allows local users to interrupt exrmultipart conversion with a crafted EXR file. The convert function multiplies untrusted data-window dimensions and computes the pixel-base offset in 32-bit signed integers, allowing both calculations to overflow. A local user must supply the file to exrmultipart; the demonstrated consequence is a sanitizer-detected conversion failure, not code execution.
