  2. Vulnerabilities (CVE)
  3. CVE-2018-14659
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.

Type Values Removed Values Added
Summary 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. 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.
