REVIEW: https://review.gluster.org/21095 (posix: disable block and character files) posted (#1) for review on release-3.12 by Amar Tumballi
Discussion:
COMMIT: https://review.gluster.org/21095 committed in release-3.12 by "jiffin tony Thottan" with a commit message- posix: disable open/read/write on special files
In the file system, the responsibility w.r.to the block and char device
files is related to only support for 'creating' them (using mknod(2)).
Once the device files are created, the read/write syscalls for the specific
devices are handled by the device driver registered for the specific major
number, and depending on the minor number, it knows where to read from.
Hence, we are at risk of reading contents fro

CVE-2018-10923 glusterfs: I/O to arbitrary devices on storage server
The Gluster file system implements a series of file system operations in the form of remote procedure calls (RPC). They are transported over the wire using TCP, optionally protected by SSL/TLS.
The "mknod" call, derived from mknod(2), can create files pointing to devices ("device special file"). Such device files can be opened on the server using normal I/O operations. As a consequence it's possible to read arbitrary devices.
