Unspecified vulnerability in Publisher 2007 in Microsoft Office 2007 allows remote attackers to execute arbitrary code via unspecified vectors, related to a "file format vulnerability." NOTE: this information is based upon a vague pre-advisory with no actionable information. However, the advisory is from a reliable source.

PUBCONV.DLL in Microsoft Office Publisher 2007 does not properly clear memory when transferring data from disk to memory, which allows user-assisted remote attackers to execute arbitrary code via a malformed .pub page via a certain negative value, which bypasses a sanitization procedure that initializes critical pointers to NULL, aka the "Publisher Invalid Memory Reference Vulnerability".

Multiple unspecified vulnerabilities in Microsoft Office Publisher allow user-assisted remote attackers to cause a denial of service (application crash) via a crafted PUB file, possibly involving wordart.
