Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on December 3, 2015 and January 28,
2016 by the OpenSSL Project. OpenSSL is used by IBM InfoSphere Information
Server. IBM InfoSphere Information Server has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-3193
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the x86_64 Montgomery squaring procedure.
An attacker with online access to an unpatched system could exploit this
vulnerability to obtain private key information.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/108502 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2015-3194
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL
pointer dereference when verifying certificates via a malformed routine. An
attacker could exploit this vulnerability using signature verification
routines with an absent PSS parameter to cause any certificate verification
operation to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/108503 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2015-3195
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a memory leak in a malformed X509_ATTRIBUTE structure.
An attacker could exploit this vulnerability to obtain CMS data and other
sensitive information.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/108504 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-0701
DESCRIPTION: OpenSSL could allow a remote attacker to conduct
man-in-the-middle attacks, caused by the use of weak Diffie-Hellman parameters
based on unsafe primes that are generated and stored in X9.42-style parameter
files. By performing multiple handshakes using the same private DH exponent,
an attacker could exploit this vulnerability to conduct man-in-the-middle
attacks.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110234 for the current
score

Note: A fix for CVE-2014-3196 was provided in OpenSSL versions 1.0.1p and
1.0.2d and was previously addressed by IBM InfoSphere Information Server.
Workarounds and Mitigations
For CVE-2016-0701
1) Add the value 1048576 (SSL_OP_SINGLE_DH_USE) to any OpenSSLOptions (OSO)
value already used. For example, if OpenSSLOptions is not currently set, then
add "OpenSSLOptions=1048576" to their DSN. If OpenSSLOptions is currently set,
then add 1048576 to the value in use.
2) Disable the use of static DH cipher suites. If CipherList is currently set,
then add ":-DH:kEDH". Otherwise, set it to "DEFAULT:-DH:kEDH".
