Summary

OpenSSL, used by the IBM PureApplication System, has security vulnerabilities
were disclosed by OpenSSL project. The following vulnerabilities have been
addressed.

Vulnerability Details

CVEID: CVE-2017-3737
DESCRIPTION: An unspecified vulnerability in multiple Oracle products could
allow an unauthenticated attacker to cause low confidentiality impact, low
integrity impact, and high availability impact.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
136077 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2017-3738
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an overflow bug in the AVX2 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. An attacker could
exploit this vulnerability to obtain information about the private key. Note:
In order to exploit this vulnerability, the server would have to share the
DH1024 private key among multiple clients, which is no longer an option since
CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
136078 for the current score
CVSS Environmental Score*: Undefined
