      "value": "SharpZipLib (or #ziplib) is a Zip, GZip, Tar and BZip2 library. Starting version 1.0.0 and prior to version 1.3.3, a check was added if the destination file is under a destination directory. However, it is not enforced that `_baseDirectory` ends with slash. If the _baseDirectory is not slash terminated like `/home/user/dir` it is possible to create a file with a name thats begins as the destination directory one level up from the directory, i.e. `/home/user/dir.sh`. Because of the file name and destination directory constraints, the arbitrary file creation impact is limited and depends on the use case. Version 1.3.3 fixed this vulnerability."

      "value": "SharpZipLib (o #ziplib) es una biblioteca Zip, GZip, Tar y BZip2. A partir de la versi\u00f3n 1.0.0 y versiones anteriores a 1.3.3, fue a\u00f1adida una comprobaci\u00f3n de si el archivo de destino est\u00e1 bajo un directorio de destino. Sin embargo, no es exigido que \"_baseDirectory\" termine en barra. Si el directorio base no termina en barra como \"/home/usuario/dir\" es posible crear un archivo con un nombre que comienza como el directorio de destino un nivel m\u00e1s arriba del directorio, por ejemplo \"/home/usuario/dir.sh\". Debido a las restricciones del nombre del archivo y del directorio de destino, el impacto de la creaci\u00f3n arbitraria de archivos es limitado y depende del caso de uso. La versi\u00f3n 1.3.3 ha corregido esta vulnerabilidad"
