Download and Installation Instructions
See KB56057 for instructions on how to download McAfee products, documentation, security updates, patches, and hotfixes.  Review the Release Notes and the Installation Guide, which you can download from the Documentation tab, for instructions on how to install these updates.
 
Product Specific Notes
  • ePolicy Orchestrator 4.6.9 and 5.x
    This issue is resolved in ePO hotfixes for 4.6.9, 5.1.3, and 5.3.1 versions. Please refer to the following Knowledge Base article for more details: KB84878 - ePolicy Orchestrator Sustaining Statement (SSC1506021) - ePO and the Logjam attack.
    • If you are running ePO 5.1.3 or 5.3.1 versions, apply hotfix EPO5x_HF1080544.zip.
    • If you are running the ePO 4.6.9 version, apply hotfix EPO469HF1080853.zip.
  • McAfee Agent
    • CVE-2015-1789: Vulnerable, but not applicable. The versions of the OpenSSL library that the agent uses for McAfeeSmartInstall and 4.8.x MAC OSX agent are vulnerable but not exploitable in agent operations.
    • CVE-2015-1791: Vulnerable, but not applicable. The versions of the OpenSSL library that the agent uses for McAfeeSmartInstall and 4.8.x MAC OSX agent are vulnerable but not exploitable considering the usage in agent operations.
     
  • McAfee Asset Manager (MAM)
    • CVE-2015-4000: Vulnerable, Hotfix "mam_hotfix8.sh" released on October 28, 2015 fixes this vulnerability.
    • CVE-2015-2808: Vulnerable, Hotfix "mam_hotfix_pack7.sh" released on July 24, 2015 fixes this vulnerability.
  • McAfee Email Gateway (MEG) / Email and Web Security (EWS)
    • If you are using ePO to manage your appliance, you must follow the process documented in KB82606 to avoid ePO overwriting your configuration changes.
    • McAfee recommends that you save the configuration file from the appliance and store a backup copy in a separate location. Edit a copy of the configuration file, and keep a current version in a safe place at all times.
    • For details about saving, editing, and restoring the appliance configuration file, follow the instructions in KB56323.
     
    Email Gateway 7.6:
    This issue is resolved in MEG 7.6.4, which is available by logging in to the ServicePortal at https://support.mcafee.com/downloads. Patches are cumulative; therefore, McAfee recommends that you install the latest one.

    To review the Release Notes, see PD25949.
    To review the Known Issues, see KB78950.

    Email Gateway 7.5:
    The forthcoming hotfix MEG 7.5.6.1h1074259 will include a relevant OpenSSL update. 7.5.6.1h1074259 will also disable EXPORT ciphers by default.

    Email and Web Security 5.6:
    The forthcoming hotfix EWS 5.6h1054075 will include a relevant OpenSSL update.

    Until the hotfix is made available, to avoid this vulnerability, disable the EXPORT ciphers. Steps to do this are listed in the Workaround section of this article.
      
  • Network Security Platform (NSP)
    Current NSP SW is vulnerable (via SSH) but not exploitable given the 2-step authentication required. The upcoming NSP 8.1 release in July will not be vulnerable (M & NS).

Workaround

For all vulnerable products - Install the provided hotfix/patch/version updates.

McAfee Email Gateway (MEG) / Email and Web Security (EWS)

IMPORTANT: To work around this vulnerability, disable the EXPORT ciphers. This workaround is needed only to handle clients that have not yet been patched.
  1. Open the appliance management console.
  2. Click System, System Administration, Backup and Restore.
  3. Save a copy of the configuration file.
  4. Create a new directory on your client.
  5. Extract smtp-config.xml from the saved configuration file into the new directory and create a backup copy of this file.

    NOTE: Ensure that you do not extract the full .zip file, only the XML to be edited. Extracting the full configuration can cause corruption in the configuration.
     
  6. Open the smtp-config.xml file with Notepad or another plain text editor.
  7. Disable EXPORT ciphers:
    1. Locate the entry: ForbiddenCiphers
    2. Add the line <Attr name="1" value="EXPORT"/> under the XML node as shown below:
      <ForbiddenCiphers>
      <Attr name="0" value="aNULL"/>
      <Attr name="1" value="EXPORT"/></ForbiddenCiphers>
       
    3. Save smtp-config.xml. If prompted, select .txt and ignore any warnings about removing the formatting.
       
      IMPORTANT: If you save smtp-config.xml in a rich text format, the data will be corrupted.
     
  8. Update the configuration .zip file with the modified smtp-config.xml. Use WinZip or an equivalent application that works with long filenames.
     
    NOTE: If you use WinZip, ensure that the full path info option is not enabled.
     
  9. Restore the modified .zip file to the appliance via the Backup and Restore page.
  10. Click Apply Changes.
Mitigations
None

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, please visit the CVSS website at: http://www.first.org/cvss/.

When calculating CVSS v2 scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by successful exploitation of the issue being scored.

CVSS v3 scoring is in final review as of March 2015. CVSS v2 will be replaced with CVSS v3 when v3 is fully approved.
