Description:
------------
If the input data has an inner boundary that contains a subset of the outer boundary the _boundarySplit function will incorrectly parse the data.
For example:
Content-Type: multipart/mixed; boundary="abc"
--abc
Content-Type: multipart/mixed; boundary="abc_a"
--abc_a
inner
--abc_a--
outer
--abc--
...will return 'abc_a' as being at the same level as 'abc' and additionally create some garbage nodes.
Test script:
---------------
function _boundarySplit($input, $boundary) {
- $tmp = explode('--' . $boundary, $input);
+ $tmp = preg_split("/--$boundary(\b|--)/", $input);

Changing PHP/OS version to Irrelevant. Also the 'test script' is actually the diff required to fix the problem. Ie, using preg_split instead of explode.
