webpki has a certificate revocation enforcement bug
There is a certificate revocation enforcement bug in rustls-webpki CRL processing. when both the certificate CRL distribution point and the CRL issuing distribution point contain multiple URI names, IssuingDistributionPoint::authoritative_for() reuses one-shot DER iterators across nested comparisons. If the only matching URI pair appears later in both sequences, the implementation misses the match, treats the CRL as non-authoritative, and under UnknownStatusPolicy::Allow accepts a revoked certificate.
