PYSEC-2026-2844 OpenEXR has use after free in PyObject_StealAttrString
Summary There is a use-after-free in PyObjectStealAttrString of pyOpenEXRold.cpp. This bug was found with ZeroPath. Details The legacy adapter defines PyObjectStealAttrString that calls PyObjectGetAttrString to obtain a new reference, immediately decrefs it, and returns the pointer. Callers then...
PYSEC-2026-2851 OpenEXR has buffer overflow in PyOpenEXR_old's channels() and channel()
Summary A memory safety bug in the legacy OpenEXR Python adapter the deprecated OpenEXR.InputFile wrapper allow crashes and likely code execution when opening attacker-controlled EXR files or when passing crafted Python objects. Integer overflow and unchecked allocation in InputFile.channel and...
PYSEC-2026-2847 OpenEXR: integer overflow to OOB write in uncompress_b44_impl()
Summary The B44/B44A decoder in OpenEXR reconstructs row pointers into a scratch buffer using int. When the channel width nx is large enough, the product y nx overflows int, causing the row pointer to wrap before the start of the scratch buffer. Subsequent memcpy calls then write decoded pixel...

OpenEXR: OpenEXR: Information disclosure and denial of service via malformed EXR files
A flaw was found in OpenEXR. A remote attacker could exploit a vulnerability in the IDManifest::init function when processing specially crafted EXR files. The function attempts to reconstruct strings from a prefix-compressed representation. If a previous string exceeds 255 bytes, the subsequent...
OpenEXR: OpenEXR: Arbitrary code execution via integer overflow in image resizing
A flaw was found in OpenEXR, an image storage format library for the motion picture industry. An integer overflow vulnerability exists in the ImageChannel::resize function, which can be triggered when processing a specially crafted OpenEXR image file through the OpenEXRUtil public API. This can...

PYSEC-2026-1749 OpenEXR Out-Of-Memory via Unbounded File Header Values
Summary The OpenEXR file format defines many information about the final image inside of the file header, such as the size of data/display window. The application trusts the value of dataWindow size provided in the header of the input file, and performs computations based on this value. This may...
PYSEC-2026-1748 OpenEXR ScanLineProcess::run_fill NULL Pointer Write In "reduceMemory" Mode
Summary When reading a deep scanline image with a large sample count in reduceMemory mode, it is possible to crash a target application with a NULL pointer dereference in a write operation. Details In the ScanLineProcess::runfill function, implemented in...
PYSEC-2026-1747 OpenEXR Heap-Based Buffer Overflow in Deep Scanline Parsing via Forged Unpacked Size
Summary The OpenEXRCore code is vulnerable to a heap-based buffer overflow during a write operation when decompressing ZIPS-packed deep scan-line EXR files with a maliciously forged chunk header. Details When parsing STORAGEDEEPSCANLINE chunks from an EXR file, the following code from...
