It is possible to execute arbitrary code on the remote Windows host due to flaws in its SMB implementation.


The remote host is affected by a vulnerability in the SMB server that may allow an attacker to execute arbitrary code or perform a denial of service against the remote host. This vulnerability depends on access to a Windows file share, but does not necessarily require credentials.


Microsoft has released a set of patches for Windows XP, Vista, 2008, 7, and 2008 R2.
