title: Denial of Service (DoS) via the ‘printf’ Search Function
description: In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can use the `printf` SPL function to perform a denial of service (DoS) against the Splunk Enterprise instance.
problem types: The software does not properly control the allocation and maintenance of a limited resource thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.
