Vulnerability Details

CVE-ID: CVE-2014-3512
Description: OpenSSL is vulnerable to a denial of service, caused by an internal buffer overrun. A remote attacker could exploit this vulnerability using invalid SRP parameters sent from a malicious server or client to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95158&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3509
Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95159&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3506
Description: OpenSSL is vulnerable to a denial of service, caused by an error when processing DTLS handshake messages. A remote attacker could exploit this vulnerability to consume an overly large amount of memory.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95160&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3507
Description: OpenSSL is vulnerable to a denial of service. By sending specially-crafted DTLS packets, a remote attacker could exploit this vulnerability to leak memory and cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95161&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3511
Description: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95162&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3505
Description: OpenSSL is vulnerable to a denial of service, caused by a double-free error when handling DTLS packets. A remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95163&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3510
Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability using a malicious handshake to cause the client to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95164&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3508
Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in OBJ_obj2txt. If applications echo pretty printing output, an attacker could exploit this vulnerability to read information from the stack.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95165&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVE-ID: CVE-2014-5139
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when an SRP ciphersuite is specified without being properly negotiated with the client. A remote attacker could exploit this vulnerability to cause the client to crash.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95166&gt; for more information

Affected Products and Versions

GPFS V3.5.0.11 or later levels of V3.5 on Windows

Remediation/Fixes

In GPFS V3.5.0.20 dated October 2014, IBM upgraded to OpenSSL 1.0.1i to address this vulnerability. System administrators should update their systems to GPFS V3.5.0.20 by following the steps below.

1. Download the GPFS 3.5.0.20 update package dated October 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 1.0.1i.

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
