A new vulnerability affecting the widely used Samba software has been released. This vulnerability could allow a user to upload a shared library to a writeable share on a vulnerable Samba server and result in the server executing the uploaded file. This currently affects all versions of Samba 3.5.0 (released March of 2010) and later. A patch has already been released to address the issue. There is a mitigation available within the configuration of the Samba itself. Adding the argument nt pipe support = no to the global section of the smb.conf file will also mitigate the threat.”]
