CVE-2018-10904: High severity centos glusterfs vulnerability
GlusterFS does not properly sanitize file paths in the "trusted.io-stats-dump" extended attribute (xattr) as used by the "debug/io-stats" translator. The value of this extended attribute is not properly sanitized and can be exploited by an attacker to create files in arbitrary locations and subsequently execute arbitrary code. To exploit this an attacker would require sufficient access to modify the extended attributes of files on a Gluster volume.
