CVE-2022-41716 Information

Description

Due to unsanitized NUL values attackers may be able to maliciously set environment variables on Windows. In syscall.StartProcess and os/exec.Cmd invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example the environment variable string \A=B\x00C=D\ sets the variables \A=B\ and \C=D.
