CRL Distribution Point Scope Check Logic Error in AWS-LC

CVSS 9.1 CRITICALEPSS 0.3%CWE-299
A logic error in CRL distribution point validation in AWS-LC before 1.71.0 causes partitioned CRLs to be incorrectly rejected as out of scope, which allows a revoked certificate to bypass certificate revocation checks. To remediate this issue, users should upgrade to AWS-LC 1.71.0 or AWS-LC-FIPS-3.3.0.
