      "value": "snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. The SnappyInputStream was found to be vulnerable to Denial of Service (DoS) attacks when decompressing data with a too large chunk size. Due to missing upper bound check on chunk length, an unrecoverable fatal error can occur. All versions of snappy-java including the latest released version 1.1.10.3 are vulnerable to this issue. A fix has been introduced in commit `9f8c3cf74` which will be included in the 1.1.10.4 release. Users are advised to upgrade. Users unable to upgrade should only accept compressed data from trusted sources."

Se descubri\u00f3 que SnappyInputStream era vulnerable a ataques de denegaci\u00f3n de servicio (DoS) al descomprimir datos con un tama\u00f1o de fragmento demasiado grande. Debido a que falta la verificaci\u00f3n del l\u00edmite superior en la longitud del fragmento, puede ocurrir un error fatal irrecuperable. Todas las versiones de snappy-java, incluida la \u00faltima versi\u00f3n 1.1.10.3, son vulnerables a este problema.\nSe introdujo una soluci\u00f3n en la confirmaci\u00f3n `9f8c3cf74` que se incluir\u00e1 en la versi\u00f3n 1.1.10.4.\nSe recomienda a los usuarios que actualicen.
