Security Bulletin


Summary

Open Source OpenSSL is used by IBM Netezza Analytics. IBM Netezza Analytics has
addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2018-0732
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
sending of a very large prime value to the client by a malicious server during
key agreement in a TLS handshake. By spending an unreasonably long period of
time generating a key for this prime, a remote attacker could exploit this
vulnerability to cause the client to hang.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144658 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-2018-0737
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by a cache-timing side channel attack in the RSA Key
generation algorithm. An attacker with access to mount cache timing attacks
during the RSA key generation process could exploit this vulnerability to
recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
141679 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0739
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending specially
crafted ASN.1 data with a recursive definition, a remote attacker could exploit
this vulnerability to consume excessive stack memory.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
140847 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)

Affected Products and Versions

IBM Netezza Analytics 1.2.4, 2.0-2.3, 3.0-3.0.2, 3.2-3.2.6, 3.3-3.3.3
