NVD Description

Note: Versions mentioned in the description apply only to the upstream dtrace-modules-4.1.12-37.6.2.el7uek package and not the dtrace-modules-4.1.12-37.6.2.el7uek package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.
