CVE-2016-3739 describes a server spoofing vulnerability in cURL and libcurl versions prior to 7.49.0, specifically affecting the mbed_connect_step1 and polarssl_connect_step1 functions when using SSLv3 or TLS connections to numerical IP addresses. This medium-severity vulnerability (CVSS 5.3) has a network attack vector and high integrity impact, allowing remote attackers to spoof servers using any valid certificate, but requires user interaction and has high attack complexity. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
