Sharks has a Bias of Polynomial Coefficients in Secret Sharing
Affected versions of this crate allowed for a bias when generating random polynomials for Shamir Secret Sharing, where instead of being within the range [0, 255] they were instead in the range [1, 255]. A description from Cure53, who originally found the issue, is available: The correct method to select a random polynomial would be to select all coefficients (including the most significant coefficient) uniformly in the range 0..255 (inclusive). …
