HTTPRedirect.php in the saml2 library in SimpleSAMLphp prior to 1.15.4 has an incorrect check of return values in the signature validation utilities, allowing an malicious user to get invalid signatures accepted as valid by forcing an error during validation. This occurs because of a dependency on PHP functionality that interprets a -1 error code as a true boolean value.
