index: prevent arbitrary file creation outside entry-changes folder
Patch in master: https://review.gluster.org/#/c/glusterfs/+/21534/
Problem:
A compromised client can set arbitrary values for the GF_XATTROP_ENTRY_IN_KEY
and GF_XATTROP_ENTRY_OUT_KEY during xattrop fop. These values are
consumed by index as a filename to be created/deleted according to the key.
Thus it is possible to create/delete random files even outside the gluster
volume boundary.
Fix:
Index expects the filename to be a basename, i.e. it must not contain any
pathname components like "/" or "../". Enforce this.
Fixes: CVE-2018-14654
Fixes: bz#1646204
