Security Bulletin
Summary
Security vulnerabilities have been discovered in OpenSSL.
Vulnerability Details
CVE-ID: CVE-2014-0160
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the TLS/DTLS heartbeat functionality. An
attacker could exploit this vulnerability to expose 64k of private memory and
retrieve secret keys. An attacker can repeatedly expose additional 64k chunks
of memory. This vulnerability can be remotely exploited, authentication is
not required and the exploit is not complex. An exploit can only partially
affect the confidentially, but not integrity or availability.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
Warning: We strongly encourage you to take action as soon as possible as
potential implications to your environment may be more serious than indicated
by the CVSS score.
CVE-ID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by an implementation error in ECDSA (Elliptic Curve
Digital Signature Algorithm). An attacker could exploit this vulnerability
using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces. This
vulnerability can only be exploited locally, authentication is not required
and the exploit is not complex. An exploit can only partially affect
confidentially, but not integrity or availability.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)
Affected Products and Versions
GPFS for Windows V3.5
Remediation/Fixes
GPFS for Windows V3.4
This version of GPFS uses OpenSSH 0.9.8y which is not affected by this
vulnerability.
GPFS for Windows V3.5
If using GPFS on Windows V3.5.0.1, please upgrade to the latest 3.5 PTF level
immediately.
For GPFS on Windows V3.5.0.11 or later, the OpenSSL libraries which are
linked in OpenSSH for GPFS on Windows, have been upgraded to 1.0.1g. This
updated OpenSSH for GPFS on Windows package is available for download from
FixCentral http://www-933.ibm.com/support/fixcentral/ :
1. Download the GPFS 3.5.0.17 update package into any directory on your system.
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.
If GPFS multiclustering is configured on Windows nodes, upgrade any OpenSSL
package that may have been installed. If using OpenSSL from Shining Light
Productions (https://slproweb.com/products/Win32OpenSSL.html), get the latest
version of OpenSSL 1.0.1g which is available on their website.
Actions that should be taken:
1.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 which contains the fix
c. Restart GPFS on the node
2. Additional instructions are needed for CVE-2014-0160. The following should
be done only when all nodes, across the multiple clusters, are running with at
OpenSSL 1.0.1g level (i.e., when the above steps are completed):
a. Change the security keys used for secure communications. Refer to the
Advanced Administration Guide, Chapter 1: Accessing GPFS file systems from
other GPFS clusters", "Changing security keys" section . The steps should be
taken up to, and including the procedure to ensure that the old key is no
longer accepted
b. If SSH is used to execute remote GPFS commands, then the SSH host keys must
also be changed
c. If SSH is used to execute remote GPFS commands, then SSH user keys/passwords
must also be changed.
Warning: Your environment may require additional fixes for other products,
including non-IBM products. Please replace the SSL certificates and reset the
user credentials after applying the necessary fixes to your environment.
