A cut 'n' paste from Bink.nu.

Critical: Moderately critical
Impact: Security Bypass

Where: From remote

Software: Microsoft Internet Explorer 6

Description:
http-equiv has identified a vulnerability in Internet Explorer, allowing malicious web sites to spoof the file extension of downloadable files.

The problem is that Internet Explorer can be tricked into opening a file, with a different application than indicated by the file extension. This can be done by embedding a CLSID in the file name. This could be exploited to trick users into opening "trusted" file types which are in fact malicious files.

Secunia has created an online test:

This has been reported to affect Microsoft Internet Explorer 6.

NOTE: Prior versions may also be affected.

Solution:
Do not use "Open" file, always save files to a folder as this reveals the suspicious filename.

I've seen that before back in the day with IE5. I'm surpised they haven't fixed that by now. Well, good thing I don't use IE.

How can an exploit in the day and age of spam/IRC, and other places ppl are exposed to a never ending spam of URL's, be only "Moderately critical" when they could be clicking what they think is a harmless jpg and instead is a exe that destroys everything on there computer or turns it into a DDoS zombie?

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
