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" to trigger a state dump and create an arbitrary number of files in the server"s runtime directory.
