Sourcefire® Delivers Same Day Protection for Microsoft Tuesday Vulnerabilities

Open source innovator and SNORT® creator, Sourcefire, Inc. (Nasdaq: FIRE), a leader in network intrusion prevention, today announced that the Sourcefire Vulnerability Research Team (VRT) has delivered rules to protect Sourcefire customers and Snort users from five Microsoft vulnerabilities announced today. These vulnerabilities impact Microsoft Windows, DirectX, DirectShow, Internet Explorer and Windows Media Format Runtime.

“Throughout 2007, Sourcefire has consistently delivered comprehensive zero-day coverage for the latest threats – often protecting Sourcefire customers and Snort users before the Microsoft Tuesday vulnerabilities are disclosed,” said Matt Watchinski, Director of the Sourcefire Vulnerability Research Team. “By combining innovative security solutions with rapid response to critical vulnerabilities and threats, Sourcefire enables our customers to take a proactive approach to securing their most critical assets.”

Following Microsoft’s disclosure earlier today, the Sourcefire VRT created, tested and delivered Snort rules designed to detect attacks targeting the Microsoft vulnerabilities listed below. These new rules are included in the latest Sourcefire Security Enhancement Update (SEU) released today.
Microsoft Security Bulletin MS07-063 – Important Microsoft Windows vulnerability in Server Message Block Version 2 (SMBv2). This vulnerability could allow an attacker to tamper with data transferred via SMBv2, which could allow remote code execution in domain configurations communicating with SMBv2.
Microsoft Security Bulletin MS07-064 – Critical vulnerabilities in DirectX could allow remote code execution if a user opened a specially crafted file used for streaming media in DirectX. If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
Microsoft Security Bulletin MS07-065 – Important Message Queuing Service (MSMQ) vulnerability that could allow remote code execution in implementations on Microsoft Windows 2000 Server, or elevation of privilege in implementations on Microsoft Windows 2000 Professional and Windows XP. An attacker must have valid logon credentials to exploit this vulnerability. An attacker could then install programs; view, change, or delete data; or create new accounts.
Microsoft Security Bulletin MS07-068 — Critical Windows Media Format vulnerability could allow remote code execution if a user viewed a specially crafted file in Windows Media Format Runtime.
Microsoft Security Bulletin MS07-069 – Critical vulnerabilities could allow remote code execution if a user viewed a specially crafted Web page using Internet Explorer.
