Attack-Flow Graph

Executive Summary

This vulnerability in IBM Db2 for Linux, UNIX, and Windows allows an authenticated user to cause a denial of service by submitting a specially crafted SQL statement that includes XML with uncontrolled recursion. This means the system can be overwhelmed or crash due to excessive recursive processing triggered by the malicious input.

Impact Analysis

The vulnerability can impact you by causing a denial of service (DoS) condition on the affected IBM Db2 systems. This means that legitimate users may be unable to access the database services because the system resources are exhausted or the service is disrupted due to the uncontrolled recursion in the SQL/XML processing.
