Algo Credit Limits has addressed the applicable CVEs and included the SSL 3.0 Fallback protection (TLS_FALLBACK_SCSV) provided by OpenSSL

Vulnerability Details

CVE-ID:CVE-2014-3513
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the DTLS Secure Real-time Transport Protocol (SRTP) extension parsing code. By sending multiple specially-crafted handshake messages, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server. CVSS:
CVSS Base Score: 5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/97035&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID:CVE-2014-3567
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak when handling failed session ticket integrity checks. By sending an overly large number of invalid session tickets, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server. CVSS:
CVSS Base Score: 5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/97036&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID:CVE-2014-3568
DESCRIPTION: OpenSSL could allow a remote attacker bypass security restrictions. When configured with “no-ssl3” as a build option, servers could accept and complete a SSL 3.0 handshake. An attacker could exploit this vulnerability to perform unauthorized actions. CVSS:
CVSS Base Score: 2.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/97037&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
