Security Bulletin: Power Systems Firmware is affected by vulnerability in OpenSSL (CVE-2014-0160)

Summary

OpenSSL Heartbleed Vulnerability - April 2014

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

After applying the fix, additional instructions are needed for CVE-2014-0160.

For Flex users only, replace your SSL certificates. After updating all nodes in the chassis, you need to revoke existing SSL certificates and reissue new certificates.
For information on replacing the SSL certificate see:

<http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5095143&gt;

Users of network facing applications protected by a vulnerable version of OpenSSL should be forced to reset their passwords and force the user to re-authenticate.

This includes:

- All HMC user accounts configured for local authentication as well as those configured for Kerberos and LDAP authentication.

- Flexible Service Processor (FSP) user accounts for all managed servers.

- Any operating system user id or application password on a partition managed by the HMC when the partition is enabled for HMC remote virtual terminal (vterm) or remote 5250 console.

For further information on managing HMC users and passwords see http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/topic/p7ha1/hmchmcmanagement-administration.htm

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.
