Red Hat Security Advisory 2012-1456-01
Posted Nov 13, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1456-01 - Red Hat Storage is software only, scale-out storage that provides flexible and affordable unstructured data storage for the enterprise. GlusterFS, a key building block of Red Hat Storage, is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnects into one large, parallel network file system. Multiple insecure temporary file creation flaws were found in Red Hat Storage. A local user on the Red Hat Storage server could use these flaws to cause arbitrary files to be overwritten as the root user via a symbolic link attack.
