      "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 descubrió que SnappyInputStream era vulnerable a ataques de denegación de servicio (DoS) al descomprimir datos con un tamaño de fragmento demasiado grande. Debido a que falta la verificación del límite superior en la longitud del fragmento, puede ocurrir un error fatal irrecuperable. Todas las versiones de snappy-java, incluida la última versión 1.1.10.3, son vulnerables a este problema.\nSe introdujo una solución en el commit `9f8c3cf74` que se incluirá en la versión 1.1.10.4.\nSe recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar solo deben aceptar datos comprimidos de fuentes confiables."
