Buffer overflow in the Microsoft HeartbeatCtl ActiveX control in HRTBEAT.OCX allows remote attackers to execute arbitrary code via the Host argument to an unspecified method.

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.

Apple Safari before 3.1.1, when running on Windows XP or Vista, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a file download with a crafted file name, which triggers memory corruption.

Integer overflow in the PCRE regular expression compiler (JavaScriptCore/pcre/pcre_compile.cpp) in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to execute arbitrary code via a regular expression with large, nested repetition counts, which triggers a heap-based buffer overflow.

The DNS client in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, and Vista uses predictable DNS transaction IDs, which allows remote attackers to spoof DNS responses.

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."

Unspecified vulnerability in the kernel in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, through Vista SP1, and Server 2008 allows local users to execute arbitrary code via unknown vectors related to improper input validation. NOTE: it was later reported that one affected function is NtUserFnOUTSTRING in win32k.sys.

The HxTocCtrl ActiveX control (hxvz.dll), as used in Microsoft Internet Explorer 5.01 SP4 and 6 SP1, in Windows XP SP2, Server 2003 SP1 and SP2, Vista SP1, and Server 2008, allows remote attackers to execute arbitrary code via malformed arguments, which triggers memory corruption.

Stack-based buffer overflow 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 image file with crafted filename parameters, aka "GDI Stack Overflow Vulnerability."

The setRequestHeader method of the XMLHttpRequest object in Microsoft Internet Explorer 5.01, 6, and 7 does not block dangerous HTTP request headers when certain 8-bit character sequences are appended to a header name, which allows remote attackers to (1) conduct HTTP request splitting and HTTP request smuggling attacks via an incorrect Content-Length header, (2) access arbitrary virtual hosts via a modified Host header, (3) bypass referrer restrictions via an incorrect Referer header, and (4) bypass the same-origin policy and obtain sensitive information via a crafted request header.

The cpoint.sys driver in Panda Internet Security 2008 and Antivirus+ Firewall 2008 allows local users to cause a denial of service (system crash or kernel panic), overwrite memory, or execute arbitrary code via a crafted IOCTL request that triggers an out-of-bounds write of kernel memory.

Cross-site scripting (XSS) vulnerability in Apple Safari before 3.1, when running on Windows XP or Vista, allows remote attackers to inject arbitrary web script or HTML via a crafted URL that is not properly handled in the error page.

Heap-based buffer overflow in Object Linking and Embedding (OLE) Automation in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, Vista, Office 2004 for Mac, and Visual basic 6.0 SP6 allows remote attackers to execute arbitrary code via a crafted script request.

Use-after-free vulnerability in Microsoft Internet Explorer 6 SP1, 6 SP2, and and 7 allows remote attackers to execute arbitrary code by assigning malformed values to certain properties, as demonstrated using the by property of an animateMotion SVG element, aka "Property Memory Corruption Vulnerability."

Heap-based buffer overflow in the WebDAV Mini-Redirector in Microsoft Windows XP SP2, Server 2003 SP1 and SP2, and Vista allows remote attackers to execute arbitrary code via a crafted WebDAV response.

Unspecified vulnerability in the TCP/IP support in Microsoft Windows Vista allows remote DHCP servers to cause a denial of service (hang and restart) via a crafted DHCP packet.

Unspecified vulnerability in the kernel in Microsoft Windows XP SP2, Server 2003, and Vista allows remote attackers to cause a denial of service (CPU consumption) and possibly execute arbitrary code via crafted (1) IGMPv3 and (2) MLDv2 packets that trigger memory corruption, aka "Windows Kernel TCP/IP/IGMPv3 and MLDv2 Vulnerability."

Heap-based buffer overflow in Windows Media Format Runtime 7.1, 9, 9.5, 9.5 x64 Edition, 11, and Windows Media Services 9.1 for Microsoft Windows 2000, XP, Server 2003, and Vista allows user-assisted remote attackers to execute arbitrary code via a crafted Advanced Systems Format (ASF) file.

Stack-based buffer overflow in the DirectShow Synchronized Accessible Media Interchange (SAMI) parser in quartz.dll for Microsoft DirectX 7.0 through 10.0 allows remote attackers to execute arbitrary code via a crafted SAMI file.

The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks.
