CVE-2025-48071 OpenEXR's Forged Unpacked Size can Lead to Heap-Based Buffer Overflow in Deep Scanline Parsing

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.3.2 through 3.3.0, there is a heap-based buffer overflow during a write operation when decompressing ZIPS-packed deep scan-line EXR files...

CVE-2025-48071

OpenEXR vulnerability CVE-2025-48071 is a heap-based buffer overflow in the EXR write/decompression path for ZIPS-packed deep scanline data when a forged chunk header causes the unpacked size to be inconsistent with the actual uncompressed data. The issue resides in OpenEXR’s chunk parsing and un...

MaterialX Stack Overflow via Lack of MTLX XML Parsing Recursion Limit

Summary When parsing an MTLX file with multiple nested nodegraph implementations, the MaterialX XML parsing logic can potentially crash due to stack exhaustion. Details By specification, multiple kinds of elements in MTLX support nesting other elements, such as in the case of nodegraph elements...

Allocation of Resources Without Limits or Throttling

Overview OpenEXR is a Python bindings for the OpenEXR image file format Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via unbounded values in the dataWindow header field. An attacker can exhaust system memory or cause the application to...

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...
