Overview
Affected versions of this package are vulnerable to Incorrect Check of Function Return Value via the get_authorization_header function when processing an incoming SIP request containing an Authorization header with a realm that was not present in a previous 401 response's WWW-Authenticate header, or when an incorrect realm is received without a prior 401 response.
