Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In Orion, 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

Affected versions of this crate did not properly reset a streaming state. Resetting a streaming state, without finalising it first, creates incorrect results. The flaw was corrected by not first checking if the state had already been reset, when calling reset().
