CVE-2026-34379

OpenEXR: OpenEXR: Denial of Service due to misaligned memory write during EXR file decoding (important)

DOCUMENTATION: A flaw was found in OpenEXR, an image storage format library for the motion picture industry. A remote attacker could exploit this vulnerability by providing a specially crafted DWA or DWAB-compressed EXR file containing a FLOAT-type channel. When the file is decoded, a misaligned memory write occurs during a half-precision to single-precision floating-point (HALF→FLOAT) conversion. This can lead to a denial of service (DoS) by crashing the application on systems with strict memory alignment enforcement, such as ARM and RISC-V architectures. 

            

            MITIGATION: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
