Security Bulletin: Multiple Vulnerabilities in OpenSSL affect IBM Spectrum Protect Backup-Archive Client NetApp Services (CVE-2018-0737, CVE-2018-0732, CVE-2018-0734)

Summary

OpenSSL vulnerabilities were disclosed on April 16, 2018, June 16, 2018. and October 30, 2018 by the OpenSSL Project. OpenSSL, used by the IBM Spectrum Protect (formerly Tivoli Storage Manager) Backup-Archive Client for network connections with NetApp services, has addressed the applicable CVEs.

Vulnerability Details

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&gt;

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-2018-0732 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&gt;

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-2018-0734 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the DSA signature algorithm. An attacker could exploit this vulnerability using variations in the signing algorithm to recover the private key.
CVSS Base Score: 3.7
