Article contents:


Several McAfee products are vulnerable to the POODLE (Padding Oracle on Downgraded Legacy Encryption) vulnerability (CVE-2014-3566). This issue is rated medium severity.  See the McAfee Product Vulnerability Status lists below for the status of each product. See the McAfee Mitigations section below for immediate action.
Security researchers at Google have discovered a vulnerability in Secure Sockets Layer (SSL) 3.0 that allows attackers to decrypt encrypted connections to websites. This attack, code named POODLE (CVE-2014-3566), allows attackers to exploit a weakness in the protocol's design to grab victims' session cookies, which are used for logging into webmail and other online accounts over HTTPS. The attack is easy to perform on-the-fly using JavaScript.

This vulnerability is not tied to OpenSSL. It is in the protocol and CBC cypher algorithm. It requires a Man-In-The-Middle attack first to break into a closed system.
SSL 3.0 is 18 years old and is a weak protocol. Support for it remains widespread, including support in nearly all browsers. To work around bugs in HTTPS servers, browsers will retry failed connections with older protocol versions, including SSL 3.0. Because a network attacker can cause connection failures, they can trigger the use of SSL 3.0 and then exploit this issue.

See SB10091 for information on three SSLv3 vulnerabilities released at the same time as POODLE.

OpenSSL Security Advisory
Vulnerability ID

CVE-2014-3566 - SSL 3.0 Fallback protection (POODLE)
The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue.

OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade.

Product Specific Notes
  • CSR
    CSR is vulnerable to POODLE. By default, SSLv2 and SSLv3 are enabled on the underlying JBoss application server. Various client components are vulnerable as well.

    A hotfix has been released to fix POODLE. See KB83301.
  • DAM / DVM
    Both DAM and DVM are vulnerable. To mitigate this vulnerability, see KB83282.
  • ePO
    ePO 5.0.1 versions and later may become vulnerable, if they have been upgraded from a previous ePO 4.x version. This is due to a non-migrated Java security setting introduced in ePO 5.0.1. You can mitigate the vulnerability with ePO 5.0.1 and later by applying the following mitigation steps. ePO 5.1.2 and later has the appropriate Java security setting applied by default.

    See KB83240 for details on what manual steps are needed to protect ePO 5.0.1 and later servers against SSLv3 POODLE attacks.
  • EWS
    EWS 5.6 is vulnerable. A patch is available for download.
  • GTI Cloud / TS-SDK
    GTI Cloud and the TS SDK are both vulnerable. They will be patched after the MWG product is patched.

    McAfee GTI Proxy 2.0 provides an SSH interface for administration. The OpenSSL associated with SSH is susceptible to CVE-2014-3566 (POODLE). OpenSSL enabled communication channels for GTI File Reputations (through DTLS channels) are not susceptible to CVE-2014-3566 (POODLE). An appliance operating system update is available.
  • MAM
    MAM 6.6 is vulnerable to POODLE. MAM uses Debian Linux. Debian has not yet patched CVE-2014-3566. See https://security-tracker.debian.org/tracker/CVE-2014-3566.
  • MEG
    • MEG 7.0 is vulnerable. McAfee is investigating a workaround.
    • MEG 7.5 and MEG 7.6 are configured to use SSL 3.0 by default. Customers can change the configuration value to disable SSL v3.
    • Patches for MEG 7.3.x, 7.4.x, and 7.5.x are available for download.
    • MEG 7.6.3 has been fully released. It contains a fix for the POODLE vulnerability. For a full list of changes and upgrade instructions, see the Release Notes in PD25527. For a list of known issues, see KB81276.

OpenSSL has published updates to address these issues in OpenSSL v0.9.8zc and 1.0.1j. Customers should patch products that are using a vulnerable version of OpenSSL.


In addition to patching products, McAfee recommends that customers disable SSL 3.0 by default.  Disabling SSL 3.0 may cause compatibility and availability issues.  You must choose between security and availability when it comes to using this weak and obsolete protocol.

Action can be taken on endpoint computers by reconfiguring the browser to disable SSL 3.0.

How to Disable SSL 3.0 in Microsoft Internet Explorer:
All supported versions of Microsoft Windows implement this protocol and are affected by this vulnerability.
Microsoft Security Advisory 3009008

How to Disable SSL 3.0 in Google Chrome:
Chrome users can disable SSLv3 by using the command line flag --ssl-version-min=tls1. (Chrome used to have an entry in the preferences for that, but users thought that “SSL 3.0” was a higher version than “TLS 1.0” and would mistakenly disable the latter.)

Several McAfee products have signatures to detect or help mitigate this vulnerability. These include:

Download the latest content for each and enable the checks if they are not enabled by default.


The POODLE vulnerability was first discovered by several researchers at Google, including Bodo Möller, Thai Duong, and Krzysztof Kotowicz. See http://googleonlinesecurity.blogspot.com/2014/10/this-poodle-bites-exploiting-ssl-30.html.

These vulnerabilities were first disclosed by the OpenSSL Project in a security advisory on October 15, 2014. See https://www.openssl.org/news/secadv_20141015.txt.
