PayPal SSL Certificate Hole on IE, Chrome and Safari
Paypal users are being advised to switch browsers if they are using either Internet Explorer, Chrome, or Safari. They should use Mozilla’s Firefox instead to protect themselves from an SSL Certificate vulnerability.
Hacker on Monday published a counterfeit secure sockets layer certificate that exploits a gaping hole in a Microsoft library used by all three of those browsers. The bug was reported nine weeks ago but Microsoft has not fixed the problem yet. The hole exists in CryptoAPI. The article at The Register notes that a tool called SSLSniff can cause all of the three browsers to display spoofed pages.
“We’re working to see if there are any technical workarounds on the PayPal side which can be put into place,” said a Paypal spokeswoman.
Fortunately, Mozilla developers patched the hole a few days after Marlinspike’s demo. That means if you’re on Windows, the only way to protect yourself against this critical vulnerability is to use Firefox versions 3.5. At least until Microsoft fixes the CryptoAPI, whenever that may be.
