Impact on SA: glibc Vulnerability: CVE-2015-0235

Note: This link provides further information about this issue and lists the glibc versions affected.

HPE has investigated the CVE-2015-0235 glibc security vulnerability (GHOST) in relation to Server Automation (SA). This document provides required actions you must perform to mitigate this vulnerability.

Note: For SA 10.0x Standard Edition (aka SAVA), install the Patch update for SAVA 10.02. Download patch and instructions are provided on the HPE Software Support Self-Solve portal at:
https://softwaresupport.hpe.com/group/softwaresupport/search-result/-/facetsearch/document/LID/SRVA_00189 (HPE Passport credentials required)

SA components use glibc, which is installed on the operating system that hosts your cores, slices, and satellites.  Operating systems, ogfs binaries, .iso images, and PXE images that use glibc are vulnerable to the GHOST security threat. As a result of the HPE investigation into this threat, HPE recommends that you perform the mitigating actions described in the next section.

Immediate mitigation actions

Perform the actions in this section to address the glibc security vulnerability.

  1. Update your glibc version on the operating system that hosts your cores, slices, and satellites.
    Use one of the following links to access glibc-updating procedures for your specific platform:
    RedHat Enterprise Linux: https://access.redhat.com/articles/1332213
    SUSE Linux Enterprise: http://support.novell.com/security/cve/CVE-2015-0235.html
    Oracle Enterprise Linux: http://linux.oracle.com/cve/CVE-2015-0235.html
    Note: Oracle Solaris 10 SPARC (still supported as a platform in Hubble 9.1x versions) is not vulnerable as it does not use glibc.
  2. Perform one of the following actions:
    1. (Preferred) Complete a system reboot to clear out the memory cache. Clearing the cache makes sure that glibc-running processes will use the updated glibc version.
    2. Use the service opsware-sas restart command to restart all SA components on every core, slice, and satellite.
  3. Use the commands below to rebuild the ogfs binaries with the rewink/reload mechanism on the systems that host your cores and slices (you do not need to rebuild the ogfs binaries on systems that host satellites).
    Note: Set umask to 0022.
    # umask 0022
    # /opt/opsware/ogfs/tools/rewink
    # /opt/opsware/ogfs/tools/reload
  4. Update the following vulnerable OS provisioning .iso images as soon as HPE releases the updates:
    Library->By Folder->OS Provisioning: HPSA_linux_boot_cd.iso
    Library->By Folder->OS Provisioning: HPSA_linux_boot_cd_IA64.iso
    Library->By Folder->OS Provisioning: HPSA_linux_boot_cd_x86-64.iso

    These .iso images are used during OS provisioning staging of a Red Hat Enterprise Linux Server in a non-DHCP environment.
    HPE expects to release updated .iso images as soon as possible after Red Hat releases their images with vulnerability fixes (Red Hat versions 7.1, 6.7, and 5.12). For more information on Red Hat releases, see: https://access.redhat.com/articles/3078.
  5. Upgrade outdated vulnerable PXE boot images as soon as HPE releases the updates.
    These images are required to boot from the network during Linux OS provisioning.
    HPE expects to release updated boot images as soon as possible after Red Hat releases their updated installation images. When the updated boot images are released, use the following Knowledge Base article to install the images: KM1112458.
