CVE-2018-20999: Flaw in streaming state in orion

The vulnerability centers on improper state reset in streaming APIs. Cryptographic streaming primitives like Chacha20 and Poly1305 in Orion would logically require stateful operations with reset capabilities. The advisory specifically mentions incorrect results from reset-before-finalize patterns, which aligns with how these algorithms manage internal buffers and nonces. The high confidence comes from: 1) The CWE-682 classification indicating calculation errors 2) The reset() function being explicitly mentioned in the advisory 3) Standard cryptographic library patterns where streaming APIs require careful state management 4) Historical precedent for similar vulnerabilities in streaming cipher implementations.
