Summary

OpenSSL vulnerabilities along with SSL 3 Fallback protection 
(TLS_FALLBACK_SCSV) were disclosed on October 15, 2014 by the OpenSSL Project.
OpenSSL is used by Algo Credit Limits. 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 http://xforce.iss.net/xforce/xfdb/97035 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 http://xforce.iss.net/xforce/xfdb/97036 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 http://xforce.iss.net/xforce/xfdb/97037 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
