IBM Db2 Input Validation Error Vulnerability (CNVD-2023-9817439)

IBM Db2 is a relational database management system from International Business Machines (IBM). The system’s execution environments are mainly UNIX, Linux, IBMi, z/OS, and Windows server versions. IBM DB2 suffers from an input validation error vulnerability that stems from the susceptibility to denial-of-service attacks when using the specially crafted RUNSTATS command on tables 8TB or larger. An attacker could exploit the vulnerability to cause a DoS.
