CVE-2018-11768
In Apache Hadoop 3.1.0 to 3.1.1, 3.0.0-alpha1 to 3.0.3, 2.9.0 to 2.9.1, and 2.0.0-alpha to 2.8.4, the user/group information can be corrupted across storing in fsimage and reading back from fsimage.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
