CVE-2017-9450
The Amazon Web Services (AWS) CloudFormation bootstrap tools package (aka aws-cfn-bootstrap) before 1.4-19.10 allows local users to execute arbitrary code with root privileges by leveraging the ability to create files in an unspecified directory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
