The curl program vulnerability is related to the handling of IDN characters in hostnames, the HSTS mechanism can be bypassed,
if the hostname in the specified URL first uses IDN characters that are replaced with ASCII analogs
during IDN conversion, then in a subsequent request it does not detect the HSTS state and performs the
the transmission in clear text. Exploitation of the vulnerability could allow an attacker acting remotely,
to gain access to sensitive information.
