Microsoft has posted its monthly security update, releasing three bulletins addressing 11 vulnerabilities, none of which has yet been targeted in the wild.
Only one of the bulletins is classified as a 'critical' security risk, covering a remote code execution vulnerability in Office 2007 and 2010.
Microsoft said that an attacker could exploit the flaw by using a specially crafted Rich Text File which could trigger an error in the Outlook Preview Pane component and allow an attack.
The remaining two bulletins address errors in PowerPoint and Forefront. The PowerPoint flaw could allow an attacker to remotely execute code through the use of a specially crafted PowerPoint file.
The Forefront vulnerability could allow an attacker to obtain elevated privileges by using a specially crafted link to exploit a vulnerability in Forefront's Unified Access Gateway component.
Both bulletins are classified as 'important' and are listed as a secondary deployment priority to the 'critical' bulletin.
However, Microsoft has failed to fix a remote code execution flaw in Internet Explorer which is already being targeted in the wild.
