CVE-2026-8813: ExifReader is vulnerable to denial of service via crafted ICC `mluc` tag
When parsing an image with an embedded ICC profile that contains a crafted multiLocalizedUnicodeType (mluc) tag, ExifReader can be made to allocate memory proportional to attacker-controlled fields in the tag rather than to
the actual size of the input. Processing such an image causes excessive memory consumption and can terminate the host process (out-of-memory).
Any application that calls ExifReader.load() on untrusted images, for example, user uploads in a web service, is affected. ICC profiles are carried in JPEG, TIFF, PNG, HEIC, AVIF, JPEG XL, and WebP, so the issue is reachable from any of those formats.
