Microsoft warns of new IE zero-day attacks

Microsoft has raised an alarm for a new round of targeted malware attacks against a zero-day vulnerability in its dominant Internet Explorer browser.

The vulnerability affects all supported versions of Internet Explorer and can be exploited to launch remote code execution (drive by download) attacks, Microsoft said in an advisory.

From Microsoft’s advisory:

The vulnerability exists due to an invalid flag reference within Internet Explorer. It is possible under certain conditions for the invalid flag reference to be accessed after an object is deleted. In a specially-crafted attack, in attempting to access a freed object, Internet Explorer can be caused to allow remote code execution.

According to Symantec’s Vikram Thakur, the IE flaw is being used in a blended attack that combines social engineering (well-tailored e-mail lures) and drive-by downloads to load a backdoor Trojan on infected computers.
