CVE-2014-3509  (opens in a new tab)
CWE-362  (opens in a new tab)

How to fix?

Upgrade OpenSSL to version 1.0.109 or higher.

Overview

OpenSSL is a SSL/TLS and Crypto toolkit. Deprecated in Mac OS and gone in iOS, this spec gives your project non-deprecated OpenSSL support.

Affected versions of this package are vulnerable to Race Condition. OepnSSL is vulnerable to denial of service (DoS) attacks through memory overwrite and client application crash. If a multithreaded client connects to a malicious server using a resumed session, it is possible to trigger a race condition in the ssl_parse_serverhello_tlsext function which allows an attacker to write up to 255 bytes of freed memory.
