1) An error within the string parsing can be exploited to cause a buffer overflow when a malicious Office document containing a malformed string is opened.

2) An integer underflow error in MSO.DLL within the parsing of "Sheet Name" strings can be exploited to cause a buffer overflow when a malicious Office document is opened.

3) An error within the property handling can be exploited to cause a buffer overflow when a malicious Office document containing a malformed property is opened.
