CVE-2025-48072 (GCVE-0-2025-48072)

Vulnerability from cvelistv5 – Published: 2025-07-31 20:18 – Updated: 2025-07-31 20:37

Title

OpenEXR's Inaccurate Pointer Arithmetic can Cause an Out of Bounds Heap

Summary

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. Version 3.3.2 is vulnerable to a heap-based buffer overflow during a read operation due to bad pointer math when decompressing DWAA-packed scan-line EXR files with a maliciously forged chunk. This is fixed in version 3.3.3.

Severity

6.8 (Medium)
