Summary

GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.
Security Fix(es):
* glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)
* glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)
* glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)
* glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)
* glusterfs: File status information leak and denial of service (CVE-2018-10927)
* glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)
* glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)
* glusterfs: Files can be renamed outside volume (CVE-2018-10930)
* glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)
* glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c (CVE-2018-10914)
* glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c (CVE-2018-10913)
