Microsoft SQL Server Stored Procedure Buffer Overflow Vulnerability
(961040, CVE-2008-5416)
This vulnerability is due to an error in the Microsoft SQL Server when calling the extended stored procedure sp_replwritetovarbin with a set of crafted parameters. Successful exploitation would cause a denial of service and may allow execution of arbitrary code on a vulnerable system. Although there is currently no Microsoft patch available, SmartDefense Services provides protections to Check Point products against exploits that use this vulnerability.

Free SmartDefense 30 Day TrialSSL Certificate Forgery Attacks
This attack leverages a weakness in the MD5 algorithm, which is used to sign SSL certificates that tie authentic corporate identities to corresponding Web site addresses and public encryption keys. Researchers were able to devise a way to manipulate an official Certificate Authority (CA) and launch an attack that would forge a rogue CA that then becomes trusted by all common browsers. SmartDefense provides a protection that will detect and block SSL connections to Web sites whose certificate may have been forged using this recently discovered attack.

Internet Explorer 7 Vulnerability
(MS08-078, CVE-2008-4844)
A remote code execution vulnerability has been reported in Microsoft Internet Explorer. A remote attacker could exploit this issue by convincing a user to open a maliciously crafted HTML file with Internet Explorer, causing the browser to crash and allowing execution of arbitrary commands. SmartDefense Services provided protections to Check Point products against exploits that use this vulnerability six days before the Microsoft patch was available.

How to Install SmartDefense Updates

Best Practice: Blocking Thunder
Peer to peer Internet traffic, such as Thunder, slows critical business applications on corporate networks. It lowers employee productivity as they take time away from their work to download music and videos. This sort of traffic also significantly increases your company’s Internet communication costs and may require you to purchase additional bandwidth.

  1. Click the SmartDefense tab.
