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

Product Version Remediation/First Fix
IBM Security Proventia Network Active Bypass 1G NAB - 2.15-36, 2.16-37, 2.18-43, 3.4-23 Proventia 1G NAB Update 11 (fw3.9-34)

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.
