Doc Text: |
Cause: When SSSD was resolving a complex group structure during an initgroups operation, it used a wrong counter and could have accessed random memory
Consequence: The random memory access crashed the sssd_be process
Fix: SSSD now uses the correct group counter
Result: SSSD processes nested group structures correctly
