IBM Security Bulletin: Vulnerabilities in OpenSSL affect IBM MQ Advanced Message Security (CVE-2016-2177, CVE-2016-2178) - United States  SECURITY BULLETIN

SUMMARY
 OpenSSL vulnerabilities were disclosed on September 22 and 26, 2016 by the OpenSSL Project. OpenSSL is used by IBM MQ Advanced Message Security on the IBM i platform only. IBM MQ Advanced Message Security has addressed the applicable CVEs. 

VULNERABILITY DETAILS
CVEID: CVE-2016-2177 [http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-2177]
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the incorrect use of pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected malloc behavior, a remote attacker could exploit this vulnerability to trigger an integer overflow and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113890 [https://exchange.xforce.ibmcloud.com/vulnerabilities/113890] 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:H) 

CVEID: CVE-2016-2178 [http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-2178]
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DSA implementation that allows the following of a non-constant time codepath for certain operations. An attacker could exploit this vulnerability using a cache-timing attack to recover the private DSA key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113889 [https://exchange.xforce.ibmcloud.com/vulnerabilities/113889] for the current score
CVSS Environmental Score*: Undefined
