| Vendor description | This security update resolves one publicly disclosed and two privately reported vulnerabilities in Server Message Block Version 2 (SMBv2).

| SophosLabs comments | The significant vulnerability of the three that are addressed by this patch is CVE-2009-3103 which was publically released around the time of the September "patch Tuesday" releases. It is significant because there has been over a month for attackers to exploit this vulnerability yet we have still to see any malware that does so. That being said we would advise users to install this patch at their earliest convenience. |
