      "value": "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."

      "value": "La funci\u00f3n TIFFGetProfiles() en el archivo /coders/tiff.c llama a la funci\u00f3n strstr() lo que causa una gran lectura fuera de l\u00edmites cuando busca `\"dc:format=\\\"image/dng\\\"` dentro de \"profile\" debido al manejo inapropiado de una cadena, cuando un archivo de entrada dise\u00f1ado es proporcionado a ImageMagick. El parche usa un tipo StringInfo en lugar de una cadena C sin procesar para remediar esto. Esto podr\u00eda causar un impacto en la disponibilidad de la aplicaci\u00f3n. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9- 0"
