Description Pedro Sampaio 2018-03-08 18:09:58 UTC 
Affected versions of this package are vulnerable to Authentication Bypass. An incorrect check of return values in the signature validation utilities allows an attacker to get invalid signatures accepted as valid by forcing an error during validation.
