CVE-2026-4428
HighSummary
Błąd logiczny w walidacji punktu dystrybucji CRL w AWS-LC przed wersją 1.71.0 powoduje, że podzielone CRL są błędnie odrzucane jako poza zakresem, co pozwala na ominięcie kontroli unieważnienia certyfikatów dla unieważnionych certyfikatów.
Risk Assessment
Organizacja może być narażona na ryzyko użycia unieważnionych certyfikatów, co może prowadzić do naruszenia bezpieczeństwa i zaufania w systemie.
Recommendation
Zaleca się aktualizację do AWS-LC w wersji 1.71.0 lub AWS-LC-FIPS-3.3.0 w celu usunięcia tej podatności.

Original NVD description (English source)
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.
