Security Bulletin
Summary
OpenSSL vulnerabilities along with SSL 3 Fallback protection (TLS_FALLBACK_SCSV) were disclosed on October 15, 2014 by the OpenSSL Project. OpenSSL is used by GPFS V3.5 for Windows. GPFS V3.5 for Windows has addressed the applicable CVEs and included the SSL 3.0 Fallback protection (TLS_FALLBACK_SCSV) provided by OpenSSL.
Vulnerability Details
CVE-ID: CVE-2014-3513
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the DTLS Secure Real-time Transport Protocol (SRTP) extension parsing code. By sending multiple specially-crafted handshake messages, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.
CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97035 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3567
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak when handling failed session ticket integrity checks. By sending an overly large number of invalid session tickets, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.
CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97036 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3568
DESCRIPTION: OpenSSL could allow a remote attacker bypass security restrictions. When configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake. An attacker could exploit this vulnerability to perform unauthorized actions.
CVSS Base Score: 2.6
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97037 for more information

Affected Products and Versions
OpenSSH for GPFS V3.5 for Windows
Remediation/Fixes
In GPFS V3.5.0.21 dated November 2014, IBM upgraded OpenSSH for GPFS on Windows to use OpenSSL 1.0.1j to address this vulnerability. System administrators should update their systems to GPFS V3.5.0.21 by following the steps below.
1. Download the GPFS 3.5.0.21 update package dated November 2014 into any directory on your system. From IBM at http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=Cluster%2Bsoftware&product=ibm/power/IBM+General+Parallel+File+System&release=3.5.0&platform=Windows&function=all
2. Extract the contents of the ZIP archive so that the .msi file it includes is directly accessible to your system.
3. Follow the instructions in the README included in the update package in order to install the OpenSSH msi package. This updated OpenSSH msi package is built using OpenSSL 1.0.1j.
If GPFS multiclustering is configured on Windows nodes, upgrade all OpenSSL packages that may have been installed. The following can be done on a small group of nodes at each time (ensuring that quorum is maintained) to maintain file system availability:
a. Stop GPFS on the node
b. Install the version of OpenSSL
c. Restart GPFS on the node
Workarounds and Mitigations
