mod_dav_svn from subversion 1.7.x does not build against apache 2.4

Posted on by mario

Since the API in Apache 2.4.x has changed the mod_dav_svn module from svn doesn’t build currently. I made patch for that. There is only a small issue in subversion/mod_dav_svn/util.c

                           errscan->desc, errscan->status, errscan->error_id);
         }

Now it compiles against Apache 2.2 and Apache 2.4

 

Any feedback is welcome.

Secure apache against CVE-2011-3389 aka Beast attack

Posted on by mario

During the summer rumours about a new attack against SSL started circulating (CVE-2011-3389).
As it turns out, the attack itself was conceived years ago, deemed impractical, but it was nevertheless fixed in TLS 1.1. The new attack technique introduced a few optimizations to make it practical.

In terms of mitigation, I expect this problem will be largely addressed on the client side, despite a potential compatibility problem that may cause some TLS sites to stop working.

With this config you can avoid that attack.

SSLProtocol all -SSLv2
SSLHonorCipherOrder On
SSLCipherSuite ECDHE-RSA-AES256-SHA384:AES256-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM:!SSLV2:!eNULL

#NO Longer needed cause since IE 7 this works ;) 
#SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown

With OpenSSL 1.0.1 it must be

SSLCipherSuite ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH
