          "value": "The npm package \"tar\" (aka node-tar) before versions 4.4.18, 5.0.10, and 6.1.9 has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat calls to determine whether a given path is a directory, paths are cached when directories are created. This logic was insufficient when extracting tar files that contained both a directory and a symlink with names containing unicode values that normalized to the same value. Additionally, on Windows systems, long path portions would resolve to the same file system entities as their 8.3 \"short path\" counterparts. A specially crafted tar archive could thus include a directory with one form of the path, followed by a symbolic link with a different string that resolves to the same file system entity, followed by a file using the first form. By first creating a directory, and then replacing that directory with a symlink that had a different apparent name that resolved to the same entry in the filesystem, it was thus possible to bypass node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite. These issues were addressed in releases 4.4.18, 5.0.10 and 6.1.9. The v3 branch of node-tar has been deprecated and did not receive patches for these issues. If you are still using a v3 release we recommend you update to a more recent version of node-tar. If this is not possible, a workaround is available in the referenced GHSA-qq89-hq3f-393p."

Esto es conseguido, en parte, asegurando que los directorios extra\u00eddos no sean enlaces simb\u00f3licos. Adem\u00e1s, para prevenir llamadas innecesarias a las estad\u00edsticas para determinar si una ruta dada es un directorio, las rutas son almacenadas en cach\u00e9 cuando se crean los directorios. Esta l\u00f3gica era insuficiente cuando se extra\u00edan archivos tar que conten\u00edan tanto un directorio como un enlace simb\u00f3lico con nombres que conten\u00edan valores unicode que se normalizaban al mismo valor. Adem\u00e1s, en los sistemas Windows, las partes de la ruta larga se resolv\u00edan a las mismas entidades del sistema de archivos que sus hom\u00f3logos de la \\\"ruta corta\\\" de la versi\u00f3n 8.3. Un archivo tar especialmente dise\u00f1ado podr\u00eda incluir un directorio con una forma de la ruta, seguido de un enlace simb\u00f3lico con una cadena diferente que resuelve a la misma entidad del sistema de archivos, seguido de un archivo usando la primera forma. Al crear primero un directorio, y luego reemplazando ese directorio con un enlace simb\u00f3lico que tuviera un nombre aparente diferente que resolviera a la misma entrada en el sistema de archivos, era posible as\u00ed omitir las comprobaciones de enlaces simb\u00f3licos de node-tar en los directorios, permitiendo esencialmente que un archivo tar no confiable tuviera un enlace simb\u00f3lico en una ubicaci\u00f3n arbitraria y que posteriormente extrajera archivos arbitrarios en esa ubicaci\u00f3n, permitiendo as\u00ed la creaci\u00f3n y escritura excesiva arbitraria de archivos. Estos problemas se solucionaron en las versiones 4.4.18, 5.0.10 y 6.1.9. La rama v3 de node-tar ha quedado obsoleta y no ha recibido parches para estos problemas. Si todav\u00eda est\u00e1 usando una versi\u00f3n v3, le recomendamos que actualice a una versi\u00f3n m\u00e1s reciente de node-tar.
