Protection Provided by:	Security Gateway R81, R80, R77, R75
Who is Vulnerable?
Vulnerability Description	An integer overflow vulnerability exists in the OpenOffice software suite. The vulnerability is due to the way OpenOffice parses EMF images. A remote attacker could exploit this vulnerability by persuading a user to open a malicious EMF file, potentially causing arbitrary code to be injected and executed on the target system 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 behavior of the target host is entirely dependent on the intended function of the injected code.
