Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/lightningnetwork/lnd, 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

### Impact A parsing vulnerability in lnd's onion processing logic led to a DoS vector due to excessive memory allocation. ### Patches The issue was patched in lnd [v0.17.0](https://github.com/lightningnetwork/lnd/releases/tag/v0.17.0-beta). Users should update to a version >= v0.17.0 to be protected. ### References Detailed blog post: https://morehouse.github.io/lightning/lnd-onion-bomb/ Developer discussion: https://delvingbitcoin.org/t/dos-disclosure-lnd-onion-bomb/979
