JSON

cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables
the certificate CN and SAN name field verification (CURLOPT_SSL_VERIFYHOST)
when the digital signature verification (CURLOPT_SSL_VERIFYPEER) is
disabled, which allows man-in-the-middle attackers to spoof SSL servers via
an arbitrary valid certificate.

Notes

Author	Note
mdeslaur	GnuTLS backend also appears to be affected. Sent mail to curl-library list.
