Descriptions

LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.

LibRaw versiones anteriores a 0.20-RC1, carece de una comprobación de rango de tamaño de miniaturas. Esto afecta a los archivos decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, y utils/thumb_utils.cpp. Por ejemplo, malloc(sizeof(libraw_processed_image_t)+T.tlength) ocurre sin comprobar T.tlength
