CVE-2026-43903 OpenImageIO: SGI RLE decoder heap buffer overflow OIIO_DASSERT bounds checks are no-ops in release builds

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, sgiinput.cpp:265,274 use OIIODASSERT for bounds checking in the RLE decode loop. In release builds, OIIODASSERT compiles to voidsizeofx...

CVE-2026-43904 OpenImageIO: Softimage PIC RLE decoder heap buffer overflow — longCount not clamped to image width

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, softimageinput.cpp:469 mixed RLE and :345 pure RLE do not clamp the run length to remaining scanline width before writing pixels. The r...

openexr: OpenEXR: Arbitrary code execution via integer overflow in EXR file processing

A flaw was found in OpenEXR, an image storage format library for the motion picture industry. An attacker can craft a malicious EXR file that, when processed, causes an integer overflow in the CompositeDeepScanLine::readPixels function. This overflow leads to an undersized buffer allocation, whic...
