  "details" : [ "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.", "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." ],
  "statement" : "This issue did not affect Red Hat Enterprise Linux 6 and 7 as the flaw is present in glusterfs-server, which is not shipped there.\nThis flaw affects glusterfs versions included in Red Hat Virtualization 4 Hypervisor. However, in recommended configurations, the vulnerability is only exposed to hypervisor administrators and can not be exploited from virtual machines or other hosts on the network.",
  "acknowledgement" : "Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting this issue.",
