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 June 11, 2015 and December 3, 2015 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 Protection from VMware, has addressed the applicable CVEs.
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-2015-1791**
DESCRIPTION:** A double-free memory error in OpenSSL in the ssl3_get_new_session_ticket() function has an unknown impact. By returning a specially crafted NewSessionTicket message, an attacker could cause the client to reuse a previous ticket resulting in a race condition.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103609 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-3193**
DESCRIPTION:** OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the x86_64 Montgomery squaring procedure. An attacker with online access to an unpatched system could exploit this vulnerability to obtain private key information.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/108502 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-2015-3194**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when verifying certificates via a malformed routine. An attacker could exploit this vulnerability using signature verification routines with an absent PSS parameter to cause any certificate verification operation to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/108503 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-2015-3195**
DESCRIPTION:** OpenSSL could allow a remote attacker to obtain sensitive information, caused by a memory leak in a malformed X509_ATTRIBUTE structure. An attacker could exploit this vulnerability to obtain CMS data and other sensitive information.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/108504 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-2015-3196**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by a race condition when PSK identity hints are received by a multi-threaded client and the SSL_CTX structure is updated with the incorrect value. An attacker could exploit this vulnerability to possibly corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/108505 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-2015-1794**
DESCRIPTION:** OpenSSL is vulnerable to a denial of service, caused by an error when a client receives a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0. An attacker could exploit this vulnerability to trigger a segfault and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/108539 for the current score
