On Windows, syscall.StartProcess and os/exec.Cmd did not properly
check for invalid environment variable values. A malicious
environment variable value could exploit this behavior to set a
value for a different environment variable. For example, the
environment variable string "A=B\x00C=D" set the variables "A=B" and
"C=D".
Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this
issue.
This is CVE-2022-41716 and Go issue https://go.dev/issue/56284.
This Go release also fixes https://github.com/golang/go/issues/56309, a
runtime bug which can cause random memory corruption when a goroutine
exits with runtime.LockOSThread() set. This fix is necessary to unblock
work to replace certain uses of pkg/reexec with unshared OS threads.
