Description

The darwinssl_connect_step1 function in lib/vtls/curl_darwinssl.c in libcurl 7.31.0 through 7.39.0, when using the DarwinSSL (aka SecureTransport) back-end for TLS, does not check if a cached TLS session validated the certificate when reusing the session, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

Affected products

• macOS: through 10.10.4
• curl: 7.31.0, 7.32.0, 7.33.0, 7.34.0, 7.35.0, 7.36.0 (+4)
