## Description

Creation of a temporary file in a directory with insecure permissions in the FPGA management tool installation component in AWS FPGA Development Kit (aws-fpga) before 2.3.4 might allow local users to execute arbitrary code with root privileges via crafted shell content placed at a predictable path in a world-writable temporary directory, which the installation step reads after elevating its own privileges.



To remediate this issue, users should upgrade to version 2.3.4.
