Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

Git before 2.19.2 on Linux and UNIX executes commands from the current working directory (as if '.' were at the end of $PATH) in certain cases involving the run_command() API and run-command.c, because there was a dangerous change from execvp to execv during 2017.(CVE-2018-19486)

Solution

Run 'yum update git' to update your system.
