This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle MySQL Cluster. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of Data Node jobs. The issue results from the lack of proper validation of user-supplied data, which can result in a access past the end of an array. An attacker can leverage this vulnerability to execute code in the context of the service account.
