Microsoft IIS FTP vulnerability and IPS

With no patch in site for Microsoft's latest vulnerability in its FTP service, you would have thought that IPS vendors would be shouting from the rooftops how their products can protect their clients systems. Surprisingly, the background noise is very low. Checkpoint make a statement claiming they now protect against exploits of the vulnerability as do Snort who state that their existing rule set would already offer protection. Some of the other IPS vendors seem to be quiet on the subject, presumably because they are too busy helping their clients protect their systems. From reading some of the blog posts at Snort, it appears that it's quite easy to block individual exploits but general protection for the vulnerability is a little more complicated.
