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.

An update of the git package has been released.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:3800 advisory.

    Git is a distributed revision control system with a decentralized architecture. As opposed to centralized     version control systems with a client-server model, Git ensures that each working copy of a Git repository     is an exact copy with complete revision history. This not only allows the user to work on and contribute     to projects without the need to have permission to push the changes to their official repositories, but     also makes it possible for the user to work with no network connection.

    Security Fix(es):

    * git: Improper handling of PATH allows for commands to be executed from the current directory     (CVE-2018-19486)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.
