Descriptions

A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside the 'smbd' configured share path and gain access to another restricted server's filesystem.

Se ha encontrado una vulnerabilidad de seguimiento de enlaces simbólicos en Samba, donde un usuario puede crear un enlace simbólico que haga que 'smbd' escape de la ruta de recurso compartido configurada. Este fallo permite a un usuario remoto con acceso a la parte exportada del sistema de archivos bajo un recurso compartido a través de extensiones SMB1 unix o NFS crear enlaces simbólicos a archivos fuera de la ruta de recurso compartido configurada por 'smbd' y obtener acceso al sistema de archivos de otro servidor restringido.
