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

Severity: Critical

CVSS Score: 9.8

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.
