The Virtual DOS Machine (VDM) in the Windows Kernel in Microsoft Windows NT 4.0; 2000 SP4; XP SP2; Server 2003, 2003 SP1, and 2003 SP2; and Windows Vista before June 2006; uses insecure permissions (PAGE_READWRITE) for a physical memory view, which allows local users to gain privileges by modifying the “zero page” during a race condition before the view is unmapped.

Stack-based buffer overflow in the Universal Plug and Play (UPnP) service in Microsoft Windows XP SP2 allows remote attackers on the same subnet to execute arbitrary code via crafted HTTP headers in request or notification messages, which trigger memory corruption.

Word (or Word Viewer) in Microsoft Office 2000 SP3, XP SP3, 2003 SP2, 2004 for Mac, and Works Suite 2004, 2005, and 2006 does not properly parse certain rich text “property strings of certain control words,” which allows user-assisted remote attackers to trigger heap corruption and execute arbitrary code, aka the “Word RTF Parsing Vulnerability.”

Unspecified vulnerability in certain COM objects in Microsoft Office Web Components 2000 allows user-assisted remote attackers to execute arbitrary code via vectors related to DataSource that trigger memory corruption, aka “Office Web Components DataSource Vulnerability.”
