Rise Security in Brazil got an Asus Eee PC and says: "the first thing that caught our attention was the running smbd process. Retrieving the the smbd version, we discovered that it runs a vulnerable version of Samba." Whoops!
Rise used an exploit that it demonstrated last year on Mac OS X. Computerworld says: "the vulnerability was disclosed May 14 and patched that same day by the Samba community".
