Description

Reentrancy issue with a shared object, atypical use case of concurrent CRL loads with one shared CertManager

Fixes crl-load-race-uaf in zd 21992

Testing

No test added due to the non-deterministic nature of the failure. Multithreaded test could silently pass, or fail in an unrepeatable way, at random.

Checklist

  • added tests
  • updated/added doxygen
  • updated appropriate READMEs
  • Updated manual and documentation
