Probably no.

The older algorithm used in 6.1 looks like
  -----------------
if (trusted) {
	variable = getenv(NAME);
         ....
  -----------------

The affected algorithm looks like:
  -----------------
if (!trusted) {
	unsetenv(NAME);
	...
};
variable = getenv(NAME);
  -----------------

As far as I know such change has been MFCed into 6.3, 6.4, 7.x but not 
into 6.1. So 6.1 should not be affected by this bug (but remain 
vulnerable to problem that triggered the change of old algorithm to new).
