ELEMENTS.DLL in Microsoft Visio 2002 SP2, 2003 SP3, and 2007 SP2 does not properly parse structures during the opening of a Visio file, which allows remote attackers to execute arbitrary code via a file containing a malformed structure, aka "Visio Data Type Memory Corruption Vulnerability."

The LZW stream decompression functionality in ORMELEMS.DLL in Microsoft Visio 2002 SP2, 2003 SP3, and 2007 SP2 allows remote attackers to execute arbitrary code via a Visio file with a malformed VisioDocument stream that triggers an exception handler that accesses an object that has not been fully initialized, which triggers memory corruption, aka "Visio Object Memory Corruption Vulnerability."

Microsoft Visio 2003 SP3 and 2007 SP2 does not properly validate objects in memory during Visio file parsing, which allows remote attackers to execute arbitrary code via a crafted file, aka "Move Around the Block RCE Vulnerability."

Microsoft Visio 2003 SP3, 2007 SP2, and 2010 Gold and SP1 does not properly validate objects in memory during Visio file parsing, which allows remote attackers to execute arbitrary code via a crafted file, aka "pStream Release RCE Vulnerability."
