24 May 2007 ~ ComputerWeekly - "Microsoft has confirmed Wednesday that it is looking into reports of a new Office zero-day flaw attackers could exploit to cause a denial of service or run malicious code on targeted Windows machines. Antivirus giant Symantec released an email advisory on the flaw to customers of its DeepSight threat management system early afternoon US time on 23 May. A couple hours later, a Microsoft spokesperson confirmed the company is investigating the report. At issue is a buffer overflow flaw in Office 2000's UA ActiveX control. Because of the flaw, the application fails to properly check user-supplied data before copying it into a poorly-sized buffer, Symantec said..." (Exploit code has been posted.) "...Symantec recommends users mitigate the threat by disabling ActiveX scripting in Internet Explorer, or set the kill bit on CLSID:8936033C-4A50-11D1-98A4-00A0C90F27C6."

Depending on the host operating system, the virus will perform different actions to infect the target machine. In this case, it downloads a lewd image of a scantily clad woman and a dude in a big ol' bunny suit. It's not the first or last attempt at such cross-platform virus writing (or the inclusion of bizarre graphics in malware) but the limitation of seeing much of this cross-platform work lies in the fact that few applications are widely deployed and run on multiple operating systems..."
