Vulnerability from cvelistv5 – Published: 2026-10-01 03:43 – Updated: 2026-10-01 19:07

Title

Gegl: gegl04: gegl: out-of-bounds read in the radiance hdr uncompressed scanline decoder

Summary

A flaw was found in GEGL. The Radiance HDR loader reads past the end of a memory-mapped image when an uncompressed scanline is shorter than the width declared in the file header. Opening a crafted HDR file crashes the application that uses the loader.

Severity

5.5 (Medium)
