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. 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
Products: IBM Security Network Protection (XGS) models 3100, 4100, 5100
Firmware versions: 5.1, 5.1.1, 5.1.2
Remediation/Fixes
The following IBM Threat Fixpacks have the fixes for these vulnerabilities.
5.1.0.0-ISS-XGS-All-Models-Hotfix-FP0008 for IBM Security Network Protection
products at version 5.1
http://www-933.ibm.com/support/fixcentral/swg/doSelectFixes?options.selectedFixes=5.1.0.0-ISS-XGS-All-Models-Hotfix-FP0008&continue=1
5.1.1.0-ISS-XGS-All-Models-Hotfix-FP0003 for IBM Security Network Protection
products at version 5.1.1
http://www-933.ibm.com/support/fixcentral/swg/doSelectFixes?options.selectedFixes=5.1.1.0-ISS-XGS-All-Models-Hotfix-FP0003&continue=1
5.1.2.0-ISS-XGS-All-Models-Hotfix-FP0004 for IBM Security Network Protection
products at version 5.1.2
http://www-933.ibm.com/support/fixcentral/swg/doSelectFixes?options.selectedFixes=5.1.2.0-ISS-XGS-All-Models-Hotfix-FP0004&continue=1
For users at IBM Security Network Protection products version 5.1.2, updating
to Firmware version 5.1.2.1 will also fix these vulnerabilities
After applying the fix, additional instructions are needed for CVE-2014-0160:
1. Replace your SSL Certificates.
You need to revoke existing SSL certificates and reissue new
certificates. You need to be sure not to generate the new certificates
using the old private key and create a new private key (ie using
"openssl genrsa") and use that new private key to create the new
certificate signing request (CSR).
2. Reset User Credentials
Users of network facing applications protected by a vulnerable version
of OpenSSL should be forced to reset their passwords and should revoke
any authentication or session related cookies set prior to the time
OpenSSL was upgraded and force the user to re-authenticate.
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.
Workarounds and Mitigations
Turn off XGS outbound SSL Inspection
