* Test for CVE-2015-1793 (Alternate Chains Certificate Forgery)
*
* Chain is as follows:
*
* rootCA (self-signed)
* |
* interCA
* |
* subinterCA subinterCA (self-signed)
* | |
* leaf ------------------
* |
* bad
*
* rootCA, interCA, subinterCA, subinterCA (ss) all have CA=TRUE
* leaf and bad have CA=FALSE
*
* subinterCA and subinterCA (ss) have the same subject name and keys
*
* interCA (but not rootCA) and subinterCA (ss) are in the trusted store
* (roots.pem)
* leaf and subinterCA are in the untrusted list (untrusted.pem)
* bad is the certificate being verified (bad.pem)
*
* Versions vulnerable to CVE-2015-1793 will fail to detect that leaf has
* CA=FALSE, and will therefore incorrectly verify bad
