Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-130: Improper Handling of Length Parameter Inconsistency, where the product parses a formatted message or structure, but it does not handle or incorrectly handles a length field that is inconsistent with the actual length of the associated data. In Rosenpass, 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 validate the size of buffers when attempting to decode messages. This allows an attacker to trigger a panic by sending a UDP datagram with a 1 byte payload over network. This flaw was corrected by validating the size of the buffers before attempting to decode the message.
