How to fix?

This issue was patched in ALAS2023-2026-1655.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mount-s3-debuginfo package and not the mount-s3-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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.
