Synopsis

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

Description

The remote host is affected by several vulnerabilities in the SMB server that may allow an attacker to execute arbitrary code or perform a denial of service against the remote host.

These vulnerabilities depend on access to a shared drive, but do not necessarily require credentials.

Solution

Microsoft has released a set of patches for Windows 2000, XP, 2003, Vista, 2008, 7, and 2008 R2.
