Technical details
An integer overflow in the scimgdataloader_tiff component fails to validate tile dimensions before calculating buffer sizes, leading to a heap overflow. The vulnerability is triggered when processing tiled TIFF files with large width, height, and sample values; no user interaction beyond opening a malicious file is required, and the fix validates tile dimensions and uses safe size functions.
