CVE-2014-7187 and CVE-2014-6278

[Jack]

As title, what difference between CVE-2014-7187 and CVE-2014-6278 ?
In CVE-2014-7187
<http://lists.gnu.org/archive/html/bug-bash/2014-10/msg00140.html> says,
the test case is probe='() { echo vulnerable; }' bash -c probe
but in Shellshocker <https://shellshocker.net/#systemtest> CVE-2014-6278
, both of them seems equally
.
