Enhancements

• This PTF disables SSLv3 protocol on HMC user interfaces.  It uses only TLSv1.2 for HMC/FSP connections for server firmware levels that support TLSv1.2.  After applying this PTF, remote access to the HMC (Browser, ASM, vterm, 5250 console) will require clients that support TLSv1.0 or TLSv1.2.
  
  

Security Fixes

This PTF includes fixes for the following security vulnerabilities:

• Fix for GNU C library (glibc) vulnerability that has been referred to as GHOST: CVE-2015-0235
  

• openssl security fixes for: CVE-2014-3570, CVE-2014-3571, CVE-2014-3572, CVE-2014-8275, CVE-2014-3569, CVE-2015-0205, CVE-2015-0206

General fixes

• Fixed an issue where after an HMC upgrade, lshmcencr may list no active ciphers with weak ciphers enabled on the web GUI.
• Fixed a problem where the GUI and lshmc -V  output may not show PTF information correctly for all applied PTFs.
• Fixed a problem where serviceable events E35A0017 and E35A0016  are reported.
• Fixed a problem where intermittently, a POWER8 server with firmware EC level 01AF820 may go to a No Connection state with connection_error_code of  02FF-0003-008087E9 after a FSP restart.

Restrictions :

• Currently in legacy security mode of HMC, it supports only TLSv1.0 Protocol only, not TLSv1.1 nor TLSv1.2. When moved to NIST SP800-131a security mode, it supports only TLSv1.2.

Notes:

1. The Install Corrective Service task now allows you to install corrective service updates from the ISO image files of these updates. You can download these ISO image files for the HMC, and then use the ISO image file to install the corrective service update. You no longer need to burn CD-R or DVD-R media to use the ISO image file to install corrective service.
2. This image requires DVD -R media.
3. To install updates over the network, select the *.iso file on the "Select Service Package" panel of the Install Corrective Service task. The HMC application extracts the files needed to install the corrective service. If you are using USB flash media, copy the *.iso file to the flash media, and then select the file when prompted.
4. The updhmc command line command has also been modified to use the *.iso file. To use the command, follow the syntax in this example:
   updhmc -t s -h <myservername> -f </home/updates/corrrective_service.iso> -u <HMC_username> -i

In all cases, the HMC application extracts the files needed to install the corrective service.
