  "details" : [ "The Gluster file system through versions 4.1.4 and 3.12 is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact.", "A buffer overflow on the heap was found in gf_getspec_req RPC request. A remote, authenticated attacker could use this flaw to cause denial of service and read arbitrary files on glusterfs server node." ],
  "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.",
