Unspecified vulnerability in Microsoft PowerPoint 2000 through 2003, possibly a buffer overflow, allows user-assisted remote attackers to execute arbitrary commands via a malformed record in the BIFF file format used in a PPT file, a different issue than CVE-2006-1540, aka "Microsoft PowerPoint Malformed Record Vulnerability."

mso.dll, as used by Microsoft PowerPoint 2000 through 2003, allows user-assisted attackers to execute arbitrary commands via a malformed shape container in a PPT file that leads to memory corruption, as exploited by Trojan.PPDropper.B, a different issue than CVE-2006-1540 and CVE-2006-3493.

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.
