Security Bulletin: Vulnerabilities in OpenSSL affect SAN Volume Controller and Storwize Family (CVE-2016-2107 CVE-2016-2108)

Security Bulletin


Summary

OpenSSL vulnerabilities were disclosed in May 2016 by the OpenSSL Project. OpenSSL is used by SAN Volume Controller and Storwize Family. SAN Volume Controller and Storwize Family products have addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2016-2107
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error when the connection uses an AES CBC cipher and the server support AES-NI. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt traffic.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112854 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-2108
DESCRIPTION:
OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by a buffer underflow when deserializing untrusted ASN.1 structures. An attacker could exploit this vulnerability to corrupt memory and trigger an out-of-bounds write and execute arbitrary code on the system.
CVSS Base Score: 8.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112853 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

Affected Products and Versions

IBM SAN Volume Controller
IBM Storwize V7000
IBM Storwize V5000
IBM Storwize V3700
IBM Storwize V3500

All products are affected when running supported releases 7.1 to 7.6. Release 7.7 is not affected.

Remediation/Fixes

IBM recommends that you fix this vulnerability by upgrading affected versions of IBM SAN Volume Controller, IBM Storwize V7000, V5000, V3700 and V3500 to the following code level or higher:

7.5.0.9
7.6.1.5

Latest SAN Volume Controller Code
Latest Storwize V7000 Code
Latest Storwize V5000 Code
Latest Storwize V3700 Code
Latest Storwize V3500 Code

For unsupported releases from 1.1 to 7.4, IBM recommends upgrading to a fixed, supported release of the product.

Workarounds and Mitigations

Although IBM recommends that you install a level of code with a fix for this vulnerability, you can mitigate, although not eliminate, your risk until you have done so by ensuring that all users who have access to the system are authenticated by another security system such as a firewall.
