0.103.11

In response to #464, we've slightly relaxed requirements for anchor_from_trust_cert() to ignore unknown extensions even if they're marked as critical. This only affects parsing a TrustAnchor from DER, for which most extensions are ignored anyway.

What's Changed

• Backport parsing trust anchors with unknown critical extensions to 0.103 by @​djc in rustls/webpki#466

0.103.10

Correct selection of candidate CRLs by Distribution Point and Issuing Distribution Point. If a certificate had more than one distributionPoint, then only the first distributionPoint would be considered against each CRL's IssuingDistributionPoint distributionPoint, and then the certificate's subsequent distributionPoints would be ignored.

The impact was that correctly provided CRLs would not be consulted to check revocation. With UnknownStatusPolicy::Deny (the default) this would lead to incorrect but safe Error::UnknownRevocationStatus. With UnknownStatusPolicy::Allow this would lead to inappropriate acceptance of revoked certificates.

This vulnerability is thought to be of limited impact. This is because both the certificate and CRL are signed -- an attacker would need to compromise a trusted issuing authority to trigger this bug. An attacker with such capabilities could likely bypass revocation checking through other more impactful means (such as publishing a valid, empty CRL.)

More likely, this bug would be latent in normal use, and an attacker could leverage faulty revocation checking to continue using a revoked credential.

This vulnerability is identified by GHSA-pwjx-qhcg-rvj4. Thank you to @​1seal for the report.
