CVE-2018-14659 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 2.17% chance of exploitation in the next 30 days.
