Subject [users@httpd] R: [users@httpd] CVE-2013-2566
Date Mon, 20 Jan 2014 12:30:05 GMT
We originally configured Apache with this directive:

SSLCipherSuite RC4-SHA

Then, then when the network scan found  the vulnerability, we modify with this


But now we have CBC and for the security requirements we have to delete RC4, CBC, and MD5
and probably other ciphers that I can't' remember.

Have you any suggestion in order to configure SSLCipherSuite to be compliant to CVE-2013-2566

Thanks in advance.

You can configure Apache to not use RC4.
