| Doc Text: |
A flaw was found in AWS-LC, a cryptographic library. A logic error in how the library validates Certificate Revocation List (CRL) distribution points can cause legitimate partitioned CRLs to be incorrectly rejected. This allows a revoked certificate to bypass certificate revocation checks, potentially leading to the acceptance of invalid or compromised certificates and compromising system security.
