Secunia Research has discovered a vulnerability in Microsoft Excel, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to an uninitialised variable being used as size argument when copying data during parsing of certain record types. This can be exploited to corrupt memory via a specially crafted file. Successful exploitation may allow execution of arbitrary code. Microsoft Excel 2002 is affected.
