CVE-2026-45696

A flaw was found in the OpenEXR image library. If an application opens a maliciously crafted EXR image file, it triggers a memory error. An attacker can use this to crash the application—causing a denial of service DoS—and potentially view sensitive information from the application's memory. Any...

CVE-2026-44663

A security flaw has been identified in OpenEXR, a widely used image format library, which may impact applications processing certain high-resolution image files. Mitigation To mitigate this issue, avoid processing untrusted HTJ2K-compressed EXR files. Restricting the handling of such files to...

Heap-based Buffer Overflow
