Summary

SSLv3 contains a vulnerability that has been referred to as the Padding 
Oracle On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in 
IBM Security Proventia Network Enterprise Scanner.

In addition, 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 IBM Security Proventia Network Enterprise 
Scanner. IBM Security Proventia Network Enterprise Scanner has addressed the 
applicable CVEs and included the SSL 3.0 Fallback protection 
(TLS_FALLBACK_SCSV) provided by OpenSSL

Vulnerability Details

CVE-ID: CVE-2014-3566

DESCRIPTION: Product could allow a remote attacker to obtain sensitive 
information, caused by a design error when using the SSLv3 protocol. A remote 
user with the ability to conduct a man-in-the-middle attack could exploit 
this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy 
Encryption) attack to decrypt SSL sessions and access the plaintext of 
encrypted connections.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

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 Base Score: 5.0
CVSS Temporal Score: http://xforce.iss.net/xforce/xfdb/97035 
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 Base Score: 5.0

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 Base Score: 2.6

IBM recommends that you review your entire environment to identify areas that 
enable the SSLv3 protocol and take appropriate mitigation and remediation 
actions. The most immediate mitigation action that can be taken is disabling 
SSLv3. You should verify disabling SSLv3 does not cause any compatibility 
issues.
