Microsoft to patch critical flaws in Windows and IE on Tuesday

microsoft logo(LiveHacking.Com) – Microsoft has released its customary advanced warning about security vulnerabilities that it plans to fix during its next Patch Tuesday. April’s update will contain nine bulletins, two of which are marked as Critical. The Critical bulletins address vulnerabilities in Microsoft Windows and Internet Explorer. The remaining seven are tagged as Important and will address issues in Microsoft Windows, Office, Anti-malware Software, and Server Software.

The IE bulletin affects all supported versions of Microsoft’s browser from IE 6 on XP to IE 10 on Windows 8 and RT. These vulnerabilities in IE could allow hackers to remotely execute arbitrary code (often used to infect a PC with malware via a drive-by download) on unpatched machines.

The Critical patches for Windows, which are also to fix remote code execution vulnerabilities, affects only the older versions of Windows from Windows 7 back to Windows XP. Windows 8, Windows Server 2012 and the version of Windows for tablets, Windows RT, are not affected.

Bulletin 7 only affects Windows 8 and Windows 8 RT and applies to some flaws in Windows Defender which could allow a hacker to run programs at an elevated privilege. Paul Henry, security and forensic analyst at Lumension, told The Register that “Windows Defender is an important security component for the new operating systems, so it’s a little concerning to see it impacted here, even if only at an ‘important’ rather than critical level. If you’re running either of those systems, I would patch this important bulletin first.

Microsoft plans to publish the bulletins on April 9, 2013 at approximately 10 a.m. PDT.
