Sources and claim methodology

Upstream source description

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.
