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 (1) VBScript (VBScript.dll) and (2) JScript (JScript.dll) scripting engines 5.1 and 5.6, as used in Microsoft Windows 2000 SP4, XP SP2, and Server 2003 SP1 and SP2, do not properly decode script, which allows remote attackers to execute arbitrary code via unknown vectors.
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."
