Vulnerability Details

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&gt; 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&gt; for the current score
CVSS Environmental Score*: Undefined

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&gt; for the current score

Affected Products and Versions

IBM Spectrum Control 5.2.8
Tivoli Storage Productivity Center 5.2.0 through 5.2.7
Tivoli Storage Productivity Center 5.1.0 through 5.1.1.9

The versions listed above apply to all licensed offerings of IBM Spectrum Control and Tivoli Storage Productivity Center, including IBM SmartCloud Virtual Storage Center Storage Analytics Engine.

Remediation/Fixes

Note: It is always recommended to have a current backup before applying any update procedure.

Apply the IBM Spectrum Control or Tivoli Storage Productivity Center fix maintenance as soon as practicable. (See Latest Downloads.)

After upgrading to the fixed version of the IBM Spectrum Control or Tivoli Storage Productivity Center server, you must also upgrade your Storage Resource Agents (SRAs). In the GUI, all existing agents will be marked as “Upgrade needed”. Follow the normal Storage Resource Agent upgrade procedure, as documented in the Knowledge Center. Once the Storage Resource Agents have been upgraded, they will resume showing their running state, i.e. “Up”.
