iTrusChina: verification errors for the roots' CRLs(ARL)
iTrusChina identified a design bug in their offline CA's ARL system that caused signature verification failures for their roots' CRLs. The issue was first reported on May 21, 2021, and iTrusChina took immediate action, halting certificate issuance and troubleshooting the problem. They discovered that the ARL information was not correctly assembled before signing, leading to inconsistencies.
