[TECHNICAL-SUPPORT] Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') (CWE ID 113)

Hi Samuel,

Tomás suggested to send this to you as long as he's on leave. It's basically the continuation of my former PR (https://github.com/topolik/liferay-portal/pull/39#issuecomment-20613336) taking Tomás' advice into account.

Thanks for reviewing!

Cheers,
László
