A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. The security update addresses the vulnerability by correcting how Microsoft Office handles objects in memory.

GDI+ in Microsoft Windows Vista SP2 and Server 2008 SP2 and Office 2003 SP3, 2007 SP2 and SP3, and 2010 Gold and SP1 does not properly validate record types in EMF images, which allows remote attackers to execute arbitrary code via a crafted image, aka "GDI+ Record Type Vulnerability."

Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, Windows 7 Gold and SP1, and Windows 8 Consumer Preview; Office 2003 SP3, 2007 SP2 and SP3, and 2010 Gold and SP1; Silverlight 4 before 4.1.10329; and Silverlight 5 before 5.1.10411 allow remote attackers to execute arbitrary code via a crafted TrueType font (TTF) file, aka "TrueType Font Parsing Vulnerability."

Untrusted search path vulnerability in Microsoft Office 2007 SP2 and 2010 allows local users to gain privileges via a Trojan horse DLL in the current working directory, aka "Insecure Library Loading Vulnerability." NOTE: this might overlap CVE-2010-3141 and CVE-2010-3142.

Microsoft Office XP SP3, Office 2003 SP3, Office 2007 SP2, Office 2010, Office 2004 and 2008 for Mac, Office for Mac 2011, and Open XML File Format Converter for Mac allow remote attackers to execute arbitrary code via a crafted Office document that triggers memory corruption, aka "Drawing Exception Handling Vulnerability."

Microsoft Office XP SP3, Office 2003 SP3, Office 2007 SP2, Office 2010, Office 2004 and 2008 for Mac, Office for Mac 2011, and Open XML File Format Converter for Mac allow remote attackers to execute arbitrary code via an Office document containing an Office Art Drawing record with crafted msofbtSp records and unspecified flags, which triggers memory corruption, aka "Office Art Drawing Records Vulnerability."

Stack-based buffer overflow in Microsoft Office XP SP3, Office 2003 SP3, Office 2007 SP2, Office 2010, Office 2004 and 2008 for Mac, Office for Mac 2011, and Open XML File Format Converter for Mac allows remote attackers to execute arbitrary code via crafted RTF data, aka "RTF Stack Buffer Overflow Vulnerability."

Buffer overflow in the Microsoft Office MSODataSourceControl ActiveX object allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long argument to the DeleteRecordSourceIfUnused method.

The CERN Image Map Dispatcher (htimage.exe) in Microsoft FrontPage allows remote attackers to determine the existence, and possibly partial contents, of arbitrary files under the web root via a relative pathname in the PATH_INFO.

The RichEdit component in Microsoft Windows 2000 SP4, XP SP2, and 2003 SP1; Office 2000 SP3, XP SP3, 2003 SP2, and Office 2004 for Mac; and Learning Essentials for Microsoft Office 1.0, 1.1, and 1.5 allows user-assisted remote attackers to execute arbitrary code via a malformed OLE object in an RTF file, which triggers memory corruption.

Unspecified vulnerability in PowerPoint in Microsoft Office 2000, Office XP and Office 2003 allows user-assisted attackers to execute arbitrary code via a crafted record in a PPT file, as exploited by malware such as Exploit:Win32/Controlppt.W, Exploit:Win32/Controlppt.X, and Exploit-PPT.d/Trojan.PPDropper.F. NOTE: it has been reported that the attack vector involves SlideShowWindows.View.GotoNamedShow.

MSO.DLL in Microsoft Office 2000, Office XP (2002), and Office 2003 allows user-assisted attackers to cause a denial of service and execute arbitrary code via multiple attack vectors, as originally demonstrated using a crafted document record with a malformed string, as demonstrated by replacing a certain "01 00 00 00" byte sequence with an "FF FF FF FF" byte sequence, possibly causing an invalid array index, in (1) an Excel .xls document, which triggers an access violation in ole32.dll; (2) an Excel .xlw document, which triggers an access violation in excel.exe; (3) a Word document, which triggers an access violation in mso.dll in winword.exe; and (4) a PowerPoint document, which triggers an access violation in powerpnt.txt. NOTE: after the initial disclosure, this issue was demonstrated by triggering an integer overflow using an inconsistent size for a Unicode "Sheet Name" string.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, as originally demonstrated using the (1) DDS Library Shape Control (Msdds.dll) COM object, and other objects including (2) Blnmgrps.dll, (3) Ciodm.dll, (4) Comsvcs.dll, (5) Danim.dll, (6) Htmlmarq.ocx, (7) Mdt2dd.dll (as demonstrated using a heap corruption attack with uninitialized memory), (8) Mdt2qd.dll, (9) Mpg4ds32.ax, (10) Msadds32.ax, (11) Msb1esen.dll, (12) Msb1fren.dll, (13) Msb1geen.dll, (14) Msdtctm.dll, (15) Mshtml.dll, (16) Msoeacct.dll, (17) Msosvfbr.dll, (18) Mswcrun.dll, (19) Netshell.dll, (20) Ole2disp.dll, (21) Outllib.dll, (22) Psisdecd.dll, (23) Qdvd.dll, (24) Repodbc.dll, (25) Shdocvw.dll, (26) Shell32.dll, (27) Soa.dll, (28) Srchui.dll, (29) Stobject.dll, (30) Vdt70.dll, (31) Vmhelper.dll, and (32) Wbemads.dll, aka a variant of the "COM Object Instantiation Memory Corruption vulnerability."

Buffer overflow in Microsoft Office XP allows remote attackers to execute arbitrary code via a link with a URL file location containing long inputs after (1) "%00 (null byte) in .doc filenames or (2) "%0a" (carriage return) in .rtf filenames.

Microsoft Excel does not warn a user when a macro is present in a Symbolic Link (SYLK) format file.
