Summary
Multiple vulnerabilities in OpenSSL affect WebSphere Message Broker and IBM
Integration Bus. The DataDirect ODBC Drivers used by WebSphere Message Broker
and IBM Integration Bus have addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-2842
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to verify that a certain memory allocation succeeds by the doapr_outch
function. A remote attacker could exploit this vulnerability using a specially
crafted string to cause an out-of-bounds write or consume an overly large
amount of resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111304 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:H)
CVEID: CVE-2016-0797
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL
pointer dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could
exploit this vulnerability using specially crafted data to cause a denial of
service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111142 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-0799
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a memory error in the BIO_*printf() functions. An
attacker could exploit this vulnerability using specially crafted data to
trigger an out-of-bounds read.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111143 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-0702
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a side-channel attack against a system based on the
Intel Sandy-Bridge microarchitecture. An attacker could exploit this
vulnerability to recover RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111144 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-0703
DESCRIPTION: OpenSSL could allow a remote attacker to bypass security
restrictions, caused by the failure to enforce that a clear-key-length value
is 0 for non-export ciphers by the SSLv2 's2_srvr.c code. When clear-key bytes
displace encrypted-key bytes, an attacker could exploit this vulnerability to
conduct a divide-and-conquer key recovery attack.
CVSS Base Score: 7.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111145 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
CVEID: CVE-2016-0704
DESCRIPTION: OpenSSL could allow a remote attacker to bypass security
restrictions. The s2_srvr.c code overwrites the wrong bytes in the master-key
when applying Bleichenbacher protection for export cipher suites. An attacker
could exploit this vulnerability using a Bleichenbacher oracle to decrypt
sessions.
CVSS Base Score: 5.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111146 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2016-2842
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to verify that a certain memory allocation succeeds by the doapr_outch
function. A remote attacker could exploit this vulnerability using a specially
crafted string to cause an out-of-bounds write or consume an overly large
amount of resources.
CVSS Base Score: 7.5

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:H)
CVEID: CVE-2016-0705
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a
double-free error when parsing DSA private keys. An attacker could exploit
this vulnerability to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111140 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
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
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)
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

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
