Security Bulletin: Vulnerabilities in OpenSSL affect IBM Spectrum Protect (formerly Tivoli Storage Manager) Client and IBM Spectrum Protect (formerly Tivoli Storage Manager) for Virtual Environments: Data Protection for VMware

Summary

OpenSSL, used by the IBM Spectrum Protect (formerly Tivoli Storage Manager) Client and IBM Spectrum Protect for Virtual Environments (formerly Tivoli Storage Manager for Virtual Environments): Data Protection from VMware, is vulnerable to two denial of service vulnerabilities which can cause the application to stop responding or crash.
NOTE1: This bulletin was updated on December 15, 2017 to add fixes for NetApp Services.
NOTE2: This bulletin was updated on February 15, 2018 to add 7.1 AIX client fix for NetApp Services.

Vulnerability Details

CVEID: CVE-2016-8610**
DESCRIPTION:** SSL/TLS protocol is vulnerable to a denial of service, caused by an error when processing ALERT packets during a SSL handshake. By sending specially-crafted packets, a remote attacker could exploit this vulnerability to cause the application to stop responding.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118296 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:H) **** ** ** CVEID: CVE-2017-3733**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by an error during a renegotiate handshake when the original handshake did not include the Encrypt-Then-Mac extension. A remote authenticated attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/122091 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)
