Descriptions

The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

El sistema de archivos Gluster hasta las versiones 3.12 y 4.1.4 es vulnerable a un ataque de denegación de servicio (DoS) mediante el uso del xattr "GF_XATTR_IOSTATS_DUMP_KEY". Un atacante autenticado remoto podría explotar esta vulnerabilidad montando un volumen Gluster y llamando repetidamente a "setxattr(2)" para desencadenar un volcado de estado y crear un número arbitrario de archivos en el directorio runtime del servidor.

A flaw was found in glusterfs server which allowed clients to create io-stats dumps on server node. A remote, authenticated attacker could use this flaw to create io-stats dump on a server without any limitation and utilizing all available inodes resulting in remote denial of service.
