Microsoft Security Tuesday Patch May 2010

Microsoft released two bulletins covering two critical vulnerabilities. Both vulnerabilities can result in remote code execution. Window's users are welcome to update these patch regularly.

MS10-030

Vulnerability in Outlook Express and Windows Mail Could Allow Remote Code Execution (978542)

This security update resolves a privately reported vulnerability in Outlook Express, Windows Mail, and Windows Live Mail. The vulnerability could allow remote code execution if a user visits a malicious e-mail server. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

MS10-031

Vulnerability in Microsoft Visual Basic for Applications Could Allow Remote Code Execution (978213)

This security update resolves a privately reported vulnerability in Microsoft Visual Basic for Applications. The vulnerability could allow remote code execution if a host application opens and passes a specially crafted file to the Visual Basic for Applications runtime. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
