Anti-virus vendor Trend Micro has spotted a Trojan in the wild attacking Windows users via the <A HREF="http://www.publish.com/article2/0,1895,1885082,00.asp">image rendering flaws</A> patched by Microsoft two days ago. The Trojan, identified as TROJ_EMFSPLOIT.A, causes the "explorer.exe" file to crash, causing the taskbar on unpatched Windows machines to disappear. Trend Micro described the exploit as a "proof-of-concept Trojan" that exploits the Graphics Rendering Engine vulnerability patched by Microsoft earlier this week. Microsoft rated the flaw as "critical" and warned that a successful exploit could let an attack take "complete control" of unpatched Windows 2000, Windows XP (including SP2), and Windows Server 2003, but the Trojan identified by Trend Micro simply causes a denial-of-service condition.
