CRITICAL

Git < 2.19.2 - Untrusted Search Path via run_command() API

Title source: llm
STIX 2.1

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.
