Summary

A flaw in the 389-ds-base LDAP Server allows a privileged user to trigger a Denial of Service condition. This vulnerability occurs during the Modify DN LDAP operation when the function's return value is not properly validated, leading to a potential NULL pointer dereference. Consequently, if a user executes a MODDN operation after an initial failure, the server may encounter a crash, impacting the availability of the service.
