Hi Bryan,
	With the latest ports, bashcheck still sees some issues with bash. Are 
these false positives on FreeBSD ?

Using
https://raw.githubusercontent.com/hannob/bashcheck/master/bashcheck

Not vulnerable to CVE-2014-6271 (original shellshock)
Not vulnerable to CVE-2014-7169 (taviso bug)
./bashcheck: line 18: 54908 Segmentation fault      (core dumped) bash 
-c "true $(printf '<<EOF %.0s' {1..79})" 2> /dev/null
Vulnerable to CVE-2014-7186 (redir_stack bug)
Test for CVE-2014-7187 not reliable without address sanitizer
Variable function parser inactive, likely safe from unknown parser bugs

	---Mike
