Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-787: Out-of-bounds Write, where the product writes data past the end, or before the beginning, of the intended buffer. In Opcua, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The package opcua from 0.0.0 until 0.11.0 is vulnerable to Denial of Service (DoS) via the ExtensionObjects and Variants objects, when it allows unlimited nesting levels, which could result in a stack overflow even if the message size is less than the maximum allowed.
