A zero-day vulnerability in Apple’s Safari browser could expose millions of Windows users to drive-by download malware attacks.  The flaw is currently unpatched.

According to an alert from Secunia, the issue is rated “highly critical” because of the risk of remote code execution attacks that can lead to complete system takeover.

From the advisory:

The vulnerability is caused due to an error in the handling of parent windows and can result in a function call using an invalid pointer. This can be exploited to execute arbitrary code when a user e.g. visits a specially crafted web page and closes opened pop-up windows.
The vulnerability is confirmed in Safari version 4.0.5 for Windows. Other versions may also be affected

    Over the last two weeks, security researchers have reported eight different zero-day vulnerabilities in Apple’s Safari browser. I found this information while reading free essays.

    Details of these vulnerabilities, all rated “high risk,” have been
    sold to Tippingpoint’s Zero Day Initiative (ZDI), a program that
    purchases the rights to vulnerability information in exchange for
    exclusivity to broker fixes with affected vendors.

    Nonsense, all of this.  Everyone knows Apple products don’t suffer from viruses. (snicker)

    I’m not such a fan of safari, I used it for about 6 months but it turned out to be a very problematic time for me, then I switched to chrome and finally I can browse web without any problems.
