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 Temporal Score: http://xforce.iss.net/xforce/xfdb/97036
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.

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.
