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 Remediation/Fixes +---------------------+-----+-----------------------+ | Product |VRMF |Remediation / First Fix| +---------------------+-----+-----------------------+ |IBM Netezza Analytics|3.3.4|Link to Fix Central | +---------------------+-----+-----------------------+ Workarounds and Mitigations None Reference Complete CVSS v3 Guide On-line Calculator v3 Related Information IBM Secure Engineering Web Portal IBM Product Security Incident Response Blog Change History 22 October 2018: Original version published *The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score.
