"statement": "This vulnerability is classified as Moderate severity rather than Important due to its reliance on specific conditions for exploitation. The integer overflow in dtdCopy affecting nDefaultAtts is limited to 32-bit platforms, reducing the attack surface as many modern systems operate on 64-bit architectures. Additionally, while the impact can lead to denial of service and potentially arbitrary code execution, the latter requires precise manipulation of the overflow condition, which may be non-trivial for attackers to achieve reliably. The constrained platform scope and the complexity of exploitation lower the overall severity, though it still poses a risk in environments where 32-bit systems are prevalent.", "threat_severity": "Moderate"}
