Security Bulletin: Multiple 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 vulnerabilities were disclosed on January 26, 2017 by the OpenSSL Project. 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 Protect for VMware, has addressed the applicable CVEs.
NOTE: This bulletin was updated on February 15, 2018 to add 7.1 AIX client fix for NetApp Services.

Vulnerability Details

CVEID: CVE-2017-3731**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read when using a specific cipher. By sending specially crafted truncated packets, a remote attacker could exploit this vulnerability using CHACHA20/POLY1305 to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121312 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)

CVEID: CVE-2017-3732**
DESCRIPTION:** OpenSSL could allow a remote attacker to obtain sensitive information, caused by a propagation error in the BN_mod_exp() function. An attacker could exploit this vulnerability to obtain information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121313 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-7055**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by an error in a Broadwell-specific Montgomery multiplication procedure. By sending specially crafted data, a remote attacker could exploit this vulnerability to trigger errors in public-key operations in configurations where multiple remote clients select an affected EC algorithm and cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118748 for the current score
