CVE-2018-14659: Debian Linux

Medium severity, CVSS 6.5. EPSS: 2.2% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Enterprise Linux Server: version 6.0 only; version 7.0 only
