[openssl-dev] Openssl Poodle Vulnerability Clarification

[Kannan Narayanasamy -X (kannanar - HCL TECHNOLOGIES LIMITED at Cisco)]

Hi Kurt,

Thanks for the details. Syslog process is based on Java and disabling SSLv3 is not possible with that. We have tried to compile openssl with SSLv3 disabled but it didn't help. Can you share the steps if you have to disable via openssl compilation.

Thanks,
Kannan Narayanasamy.

But for the ports 3333 and 4444 is connecting using SSLv3. The scanner as well report the high severity risk for those ports. In our application we are using those ports for syslog related tasks. If we change the port some other, then the scanner shows the new port in the list.

There are 2 solutions:
- Change the configuration of syslog to disable SSLv3.  Not sure
  it can actually be configured.
- Build your openssl with SSLv3 disabled.
