Overview

github.com/keep-network/keep-ecdsa is a package providing smart contracts and client behind the Keep ECDSA client

Affected versions of this package are vulnerable to Improper Input Validation. The Verifiable Secret Sharing scheme generates shares from the user’s IDs but does not properly validate them. Using a malicious ID will make other users reveal their secrets during the secret-sharing procedure. In addition, a second issue resulting from lack of validation could cause nodes to crash when sent maliciously formed user IDs.
