Description Sam Fowler 2018-09-21 01:00:20 UTC
The Gluster file system through version 4.1.4 is vulnerable to abuse of the "features/index" translator. A remote attacker with access to mount volumes could exploit this via the "GF_XATTROP_ENTRY_IN_KEY" xattrop to create arbitrary, empty files on the target server.

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.

This 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.
