Microsoft confirms zero-day bug in IE6, IE7 and IE8

Second time in two years it's had to deal with late-December vulnerabilities

By , Computerworld |  Security, ie6, ie7

In 2011, the company issued a Dec. 28 security advisory about a flaw in its ASP .Net programming language that hackers could use to cripple website servers. On Dec. 29, 2011, Microsoft released an "out-of-band," or emergency, update.

Microsoft reminded customers that IE9 and IE10 do not contain the vulnerable code, and are safe to use. Windows XP users, however, cannot use either of those browsers, as Microsoft has limited IE9 to Vista and Windows 7, and IE10 to Windows 7 and Windows 8.
