CVE-2016-2390
The FwdState::connectedToPeer method in FwdState.cc in Squid before 3.5.14 and 4.0.x before 4.0.6 does not properly handle SSL handshake errors when built with the –with-openssl option, which allows remote attackers to cause a denial of service (application crash) via a plaintext HTTP message.
