Descriptions

TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it searches for `"dc:format=\"image/dng\"` within `profile` due to improper string handling, when a crafted input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick versions prior to 7.0.9-0.

La función TIFFGetProfiles() en el archivo /coders/tiff.c llama a la función strstr() lo que causa una gran lectura fuera de límites cuando busca `"dc:format=\"image/dng\"` dentro de "profile" debido al manejo inapropiado de una cadena, cuando un archivo de entrada diseñado es proporcionado a ImageMagick. El parche usa un tipo StringInfo en lugar de una cadena C sin procesar para remediar esto. Esto podría causar un impacto en la disponibilidad de la aplicación. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9- 0
