Security Bulletin: BladeCenter Advanced Management Module (AMM) is affected 
by vulnerabilities in OpenSSL (CVE-2014-0160 and CVE-2014-0076)

Abstract

Security vulnerabilities have been discovered in OpenSSL

Content

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. It can be exploited on any system (ie. server, 
client, agent) receiving connections using the vulnerable OpenSSL library..

CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/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.

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)

Remediation/Fixes:

IBM recommends downloading and applying the following updates from IBM Fix 
Central:.
Product										Version
BladeCenter Advanced Management Module – IBM BladeCenter T Chassis		Update to v3.66D (BBET66D)
BladeCenter Advanced Management Module – BladeCenter OEM Chassis		Update to v3.66D (BPEO66D)
BladeCenter Advanced Management Module – All other IBM BladeCenter Chassis	Update to v3.66D (BPET66D)

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.

Below is specific information regarding how to replace certificates and reset 
user credentials on the AMM.
