NVD Description

Note: Versions mentioned in the description apply only to the upstream glusterfs-cli package and not the glusterfs-cli package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
