Security Bulletin
Summary
SSLv3 contains a vulnerability that has been referred to as the Padding Oracle
On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in
Connect:Enterprise For UNIX, Connect:Enterprise Command Line Client,
Connect:Enterprise HTTP Option, and Connect:Enterprise Secure Client.
Also, OpenSSL vulnerabilities were disclosed on October 15, 2014 by the
OpenSSL Project. OpenSSL is used by Connect:Enterprise For UNIX.
Connect:Enterprise For UNIX has addressed the applicable CVEs.
Vulnerability Details
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.
Connect:Enterprise Clients are not affected by this vulnerability.
CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97036 for more
information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3566
DESCRIPTION: Connect:Enterprise For UNIX 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 for the
current score

Frequently Asked Questions.
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.
Workarounds and Mitigations
For Connect:Enterprise UNIX sessions using FTP, configure the protocol
definitions to only allow TLS connections.
For Connect:Enterprise UNIX Admin, AS2 and WebDAV functionality, and for the
other products mentioned, apply the iFix above and follow the instructions in
the iFix readme file to add the -Dtlsonly=true parameter to the Java startup
line.
For transfers using Connect:EnterpriseSecure Client, ensure that the server
being connected to is configured to only allow TLS protocol.
