Description


Some security issues have been reported in Ruby, which can be exploited by malicious people to conduct spoofing attacks.

The security issues are caused due to the "net::https", "net::ftptls", "net::telnets", and "net::imap" modules not properly checking if the Common Name field provided inside SSL server certificates matches the requested hostname of a server. This can be exploited to conduct spoofing attacks.

Successful exploitation requires a MitM (Man-in-the-Middle) attack and possession of a valid certificate, which is signed by the CA specified in the client.

The security issues are reported in version 1.8.5 and 1.8.6.


Solution:
Fixed in SVN repository.

Provided and/or discovered by:
Chris Clark, iSEC Partners
Additionally affected modules reported by the vendor.
