libcurl.so is vulnerable to man-in-the-middle attack. A lack of validation of the TLS certificate and hostname in the mbed_connect_step1 function in lib/vtls/mbedtls.c and polarssl_connect_step1 function in lib/vtls/polarssl.c allows a remote attacker to spoof servers and perform man-in-the-middle attacks against the target server.
