Apple Safari before 3.1.2 on Windows does not properly interpret the URLACTION_SHELL_EXECUTE_HIGHRISK Internet Explorer zone setting, which allows remote attackers to bypass intended access restrictions, and force a client system to download and execute arbitrary files.

Unspecified vulnerability in WebKit in Apple Safari before 3.1.2, as distributed in Mac OS X before 10.5.4, and standalone for Windows and Mac OS X 10.4, allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors involving JavaScript arrays that trigger memory corruption.

Microsoft DirectX 8.1 through 9.0c, and DirectX on Microsoft XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008, does not properly perform MJPEG error checking, which allows remote attackers to execute arbitrary code via a crafted MJPEG stream in a (1) AVI or (2) ASF file, aka the "MJPEG Decoder Vulnerability."

Microsoft Windows XP SP2 and SP3, and Server 2003 SP1 and SP2, does not properly validate the option length field in Pragmatic General Multicast (PGM) packets, which allows remote attackers to cause a denial of service (infinite loop and system hang) via a crafted PGM packet, aka the "PGM Invalid Length Vulnerability."

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."

Stack-based buffer overflow in Microsoft DirectX 7.0 and 8.1 on Windows 2000 SP4 allows remote attackers to execute arbitrary code via a Synchronized Accessible Media Interchange (SAMI) file with crafted parameters for a Class Name variable, aka the "SAMI Format Parsing Vulnerability."

The Bluetooth stack in Microsoft Windows XP SP2 and SP3, and Vista Gold and SP1, allows physically proximate attackers to execute arbitrary code via a large series of Service Discovery Protocol (SDP) packets.

Heap-based buffer overflow in Apple QuickTime before 7.5 on Windows allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted packed scanlines in PixData structures in a PICT image.

Apple Safari on Mac OS X, and before 3.1.2 on Windows, does not prompt the user before downloading an object that has an unrecognized content type, which allows remote attackers to place malware into the (1) Desktop directory on Windows or (2) Downloads directory on Mac OS X, and subsequently allows remote attackers to execute arbitrary code on Windows by leveraging an untrusted search path vulnerability in (a) Internet Explorer 7 on Windows XP or (b) the SearchPath function in Windows XP, Vista, and Server 2003 and 2008, aka a "Carpet Bomb" and a "Blended Threat Elevation of Privilege Vulnerability," a different issue than CVE-2008-1032. NOTE: Apple considers this a vulnerability only because the Microsoft products can load application libraries from the desktop and, as of 20080619, has not covered the issue in an advisory for Mac OS X.

The I2O Utility Filter driver (i2omgmt.sys) 5.1.2600.2180 for Microsoft Windows XP sets Everyone/Write permissions for the "\\.\I2OExc" device interface, which allows local users to gain privileges. NOTE: this issue can be leveraged to overwrite arbitrary memory and execute code via an IOCTL call with a crafted DeviceObject pointer.

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.

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.
