- For JBOSSEAP 5.2.0, I can't find security advisories of CVE-2014-3566 for Linux platform. Where can I find this CVE for Red Hat linux?
-Some components do not provide configuration parameters that allow SSLv3 to be disabled. Currently, the following components are known to fall into this category:
It is possible to disable SSLv3 for these components by using stunnel. Stunnel provides an encryption wrapper between a remote client and a local (inetd-startable) or remote server, using the OpenSSL library for cryptography.
To disable SSLv3 on stunnel, use the following configuration parameters in the stunnel.conf file:
options = NO_SSLv2 options = NO_SSLv3
Installation and configuration of stunnel is outside the scope of this solution, please consult the man pages and system documentation for more details.
Note: Newer openldap-servers has TLSProtocolMin option. If openldap-servers is openldap-servers-2.4.39-8.el6(for RHEL6), openldap-servers-2.4.39-3.el7(for RHEL7) or later, add "TLSProtocolMin 3.1" in slapd.conf to disable SSLv3. You can refer to man slapd.conf.
A vulnerability was found in the SSLv3.0 protocol. This vulnerability allows a man-in-the-middle attacker to decrypt ciphertext using a padding oracle side-channel attack. For more information about this vulnerability, refer to the following article: POODLE: SSLv3.0 vulnerability (CVE-2014-3566)
