As expected, Microsoft today released its June 2008 security bulletin, which includes three critical, three important, and one moderate patch. Of the critical, one is for the Bluetooth stack in Windows XP and Windows Vista, one is for DirectX, and another is a cumulative update to Internet Explorer. The one moderate bulletin covers a flaw in the speech recognition feature in Windows 2000, XP, and Windows Vista. Of the important bulletins, one concerns Active Directory and another Pragmatic General Multicast (PGM)

MS08-030: Critical - Titled "Vulnerability in Bluetooth Stack Could Allow Remote Code Execution (951376)", this bulletin is critical for users of Windows XP and Windows Vista (both 32-bit and 64-bit editions). The update addresses vulnerabilities detailed in CVE-2008-1453. The patch modifies the way that the Bluetooth stack handles a large number of service description requests. Microsoft says an attacker could use this to take complete control of an affected system; install programs; view, change, or delete data; or create new accounts with full user rights.

MS08-031: Critical - Titled "Cumulative Security Update for Internet Explorer (950759)", this bulletin affects all users of Windows. However, the critical designation only applies to users of Windows XP and Windows Vista; all others are deemed moderate or important by Microsoft. The update addresses vulnerabilities in CVE-2008-1442 and CVE-2008-1544. The cumulative patch fixes a couple of vulnerabilities including one that could allow remote code execution if a user viewed a specially crafted Web page using Internet Explorer and another which could allow information disclosure if a user viewed a specially crafted Web page using Internet Explorer.

MS08-033: Critical - Titled "Vulnerabilities in DirectX Could Allow Remote Code Execution (951698)", this bulletin affects all supported editions of Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008. This update addresses the vulnerability detailed in CVE-2008-0011 and CVE-2008-1444. Microsoft says the vulnerability "could allow remote code execution if a user opens a specially crafted media file. An attacker who successfully exploited either of these vulnerabilities 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."
