A fix was pushed into the master branch but not yet published.

Overview

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the dsaVerify function. An attacker can construct signatures that can be successfully verified by any public key, leading to a signature forgery attack. This is achieved by exploiting an upper bound check issue in the checkValue function, which incorrectly checks the upper bound of the passed parameters.

Note: This vulnerability affects all places in the project that involve DSA verification of user-input signatures.
