CVE-2026-45696
Description
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 system that processes untrusted EXR files is at risk.
Statement
This flaw in the OpenEXR library allows attackers to crash applications or potentially view sensitive memory data by providing a specially crafted image file. Systems that automatically process untrusted EXR files (like asset pipelines or thumbnailers) are at the highest risk.
Mitigation
To minimize risk, avoid opening or processing EXR image files from untrusted or unknown sources. For environments that must process external files, run the handling applications within a sandboxed environment to restrict their privileges and limit the damage a potential exploit can cause.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
