Quadratic complexity when checking name constraints in crypto/x509

CVSS 7.5 HIGHEPSS 0.4%

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.
