Summary

OpenSSL vulnerabilities were disclosed on March 1, 2016 by the OpenSSL
Project. OpenSSL is used by IBM InfoSphere Master Data Management . IBM
InfoSphere Master Data Management has addressed the applicable CVEs including
the DROWN: Decrypting RSA with Obsolete and Weakened eNcryption"

Vulnerability Details

CVEID:

CVE-2016-0800

DESCRIPTION:

OpenSSL could allow a remote attacker to bypass security restrictions. By
using a server that supports SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle, an attacker could exploit this
vulnerability to decrypt TLS sessions between clients and non-vulnerable
servers. This vulnerability is also known as the DROWN attack.

CVSS Base Score: 7.4

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/111139

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-2016-0705

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

CVEID:

CVE-2016-0798

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by a memory leak in SRP
servers. An attacker could exploit this vulnerability using a specially
crafted username value to cause a denial of service.

CVSS Base Score: 3.7

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/111141

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

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

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

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

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

CVEID:

CVE-2015-3197

DESCRIPTION:

OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks,
caused by an error related to the negotiation of disabled SSLv2 ciphers by
malicious SSL/TLS clients. An attacker could exploit this vulnerability to
conduct man-in-the-middle attacks.

CVSS Base Score: 5.4
