CVE-2015-0293  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade OpenSSL to version 1.0.200 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 Improper Input Validation. OpenSSL is vulnerable to denial of service attacks. The attacks are due to a flaw in the way OpenSSL does the SSLv2 handshake messages. Therefore, when it has SSLv2 and EXPORT-grade cipher suites enabled, attackers can send malicious SSLv2 CLIENT-MASTER-Key messages to cause server failures.
