Who is Vulnerable?
Vulnerability Description OpenOffice.org is an open source office suite. The package 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 overflow vulnerability exists in the OpenOffice software suite. The vulnerability is due to the way OpenOffice parses Tagged Image File Format (TIFF) images. A remote attacker could exploit this vulnerability by persuading a user to open a malicious TIFF file, potentially causing arbitrary code to be injected and executed in the security context of the logged in user. In an attack case where code injection is not successful, all instances of the vulnerable OpenOffice application will terminate. In a more sophisticated attack scenario where code injection is successful, the behaviour of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. The affected application would also most likely stop functioning as a result of such an attack.
