Vulnerability Description	OpenOffice.org is an open source office suite. The suite includes a word processor, a spreadsheet application, a presentation creator, an illustration drawer, a desktop database, and an equation editor. The product is made available for multiple platforms and languages. An integer underflow vulnerability has been reported in OpenOffice that allows remote attackers to inject and execute arbitrary code on the target system. The vulnerability is due to an integer underflow error when parsing certain records in the document table. Remote attackers can exploit this vulnerability by enticing the target user to open a malicious Word document. In case where code injection and execution is successful, the behavior of the target is dependent on the intention of the malicious code. The injected code will execute with the privileges of the currently logged in user.
