The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.

Microsoft Internet Explorer 6 does not properly handle errors related to using the componentFromPoint method on xml objects that have been (1) incorrectly initialized or (2) deleted, which allows remote attackers to execute arbitrary code via a crafted HTML document, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy, and execute arbitrary code or obtain sensitive information, via a crafted HTML document, aka "Event Handling Cross-Domain Vulnerability."

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 does not properly validate parameters sent from user mode to the kernel, which allows local users to gain privileges via a crafted application, aka "Windows Kernel Memory Corruption Vulnerability."

Buffer overflow in gdiplus.dll in GDI+ in Microsoft Internet Explorer 6 SP1, Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, Office XP SP3, Office 2003 SP2 and SP3, 2007 Microsoft Office System Gold and SP1, Visio 2002 SP2, PowerPoint Viewer 2003, Works 8, Digital Image Suite 2006, SQL Server 2000 Reporting Services SP2, SQL Server 2005 SP2, Report Viewer 2005 SP1 and 2008, and Forefront Client Security 1.0 allows remote attackers to execute arbitrary code via a malformed WMF image file that triggers improper memory allocation, aka "GDI+ WMF Buffer Overrun Vulnerability."

gdiplus.dll in GDI+ in Microsoft Internet Explorer 6 SP1, Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, Office XP SP3, Office 2003 SP2 and SP3, 2007 Microsoft Office System Gold and SP1, Visio 2002 SP2, PowerPoint Viewer 2003, Works 8, Digital Image Suite 2006, SQL Server 2000 Reporting Services SP2, SQL Server 2005 SP2, Report Viewer 2005 SP1 and 2008, and Forefront Client Security 1.0 does not properly perform memory allocation, which allows remote attackers to execute arbitrary code via a malformed EMF image file, aka "GDI+ EMF Memory Corruption Vulnerability."

Integer overflow in GDI+ in Microsoft Internet Explorer 6 SP1, Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, Office XP SP3, Office 2003 SP2 and SP3, 2007 Microsoft Office System Gold and SP1, Visio 2002 SP2, PowerPoint Viewer 2003, Works 8, Digital Image Suite 2006, SQL Server 2000 Reporting Services SP2, SQL Server 2005 SP2, Report Viewer 2005 SP1 and 2008, and Forefront Client Security 1.0 allows remote attackers to execute arbitrary code via an image file with crafted gradient sizes in gradient fill input, which triggers a heap-based buffer overflow related to GdiPlus.dll and VGX.DLL, aka "GDI+ VML Buffer Overrun Vulnerability."

Request Validation (aka the ValidateRequest filters) in ASP.NET in Microsoft .NET Framework with the MS07-040 update does not properly detect dangerous client input, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a query string containing a "<~/" (less-than tilde slash) sequence followed by a crafted STYLE element.

Array index vulnerability in the Event System in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote authenticated users to execute arbitrary code via a crafted event subscription request that is used to access an array of function pointers.

The Event System in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 does not properly validate per-user subscriptions, which allows remote authenticated users to execute arbitrary code via a crafted event subscription request.

Microsoft Windows Vista through SP1 and Server 2008 do not properly import the default IPsec policy from a Windows Server 2003 domain to a Windows Server 2008 domain, which prevents IPsec rules from being enforced and allows remote attackers to bypass intended access restrictions.

Microsoft Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote attackers to cause a denial of service (system hang) via a series of Pragmatic General Multicast (PGM) packets with invalid fragment options, aka the "PGM Malformed Fragment Vulnerability."

Unspecified vulnerability in Apple QuickTime Player on Windows XP SP2 and Vista SP1 allows remote attackers to execute arbitrary code via a crafted QuickTime media file. NOTE: as of 20080429, the only disclosure is a vague pre-advisory with no actionable information. However, because it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Microsoft Windows XP Professional SP2, Vista, and Server 2003 and 2008 does not properly assign activities to the (1) NetworkService and (2) LocalService accounts, which might allow context-dependent attackers to gain privileges by using one service process to capture a resource from a second service process that has a LocalSystem privilege-escalation ability, related to improper management of the SeImpersonatePrivilege user right, as originally reported for Internet Information Services (IIS), aka Token Kidnapping.

Heap-based buffer overflow in the CreateDIBPatternBrushPt function in GDI in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, Vista, and Server 2008 allows remote attackers to execute arbitrary code via an EMF or WMF image file with a malformed header that triggers an integer overflow, aka "GDI Heap Overflow Vulnerability."

Microsoft XML Core Services (MSXML) 3.0 through 6.0 allows remote attackers to execute arbitrary code via the substringData method on a (1) TextNode or (2) XMLDOM object, which causes an integer overflow that leads to a buffer overflow.

Race condition in Microsoft Internet Explorer 6 SP1; 6 and 7 for Windows XP SP2 and SP3; 6 and 7 for Server 2003 SP2; 7 for Vista Gold, SP1, and SP2; and 7 for Server 2008 SP2 allows remote attackers to execute arbitrary code or perform other actions upon a page transition, with the permissions of the old page and the content of the new page, as demonstrated by setInterval functions that set location.href within a try/catch expression, aka the "bait & switch vulnerability" or "Race Condition Cross-Domain Information Disclosure Vulnerability."
