By admin | September 28, 2010
Today, Microsoft released an out-of-band security bulletin that addresses a vulnerability in ASP. Net. ASP. Net is a software component used in the Microsoft web services software, and according to the Microsoft Security Blog, affects "all versions of the . NET Framework when used on Windows Server operating systems. Windows desktop systems are listed as affected, but consumers are not vulnerable unless they are running a Web server from their computer. Zusammen mit carl zeiss begründete er die theorie des www.best-ghostwriter.com/ mikroskops und schuf weitere theoretische grundlagen für optische geräte. " The listed operating systems include Windows XP, Vista, Windows 7, Server 2003, and Server 2008.
The vulnerability has been classified as "Important," just one step below "Critical. " An "Important" rating is described by Microsoft as, "a vulnerability whose exploitation could result in compromise of the confidentiality, integrity, or availability of users data, or of the integrity or availability of processing resources. "
This is a publicly disclosed vulnerability, and attacks have already begun. The Microsoft Security Blogs notes: "Based on our comprehensive monitoring of the threat landscape, we have determined an out-of-band release is needed to protect customers as we have seen limited attacks and continued attempts to bypass current defenses and workarounds. "
System administrators should update their servers and any workstations running web services immediately. The update will be available immediately through the Microsoft Download Center, and through Windows Update and WSUS in the coming days.

64-bit Linux local kernel exploit
By admin | September 20, 2010
An announcement was made on September 19, 2010, that a vulnerability has existed in the 64-bit Linux kernel for approximately two years. The vulnerability requires local access to the server in question to exploit, but the exploit is trivial to execute. While local root access to the server is bad enough, there is also a back-door that is installed that allows remote execution of code on the exploited server.
Several Linux distributions have already published kernel updates that address the issue, with others soon to follow. There are also third-party patch and detection tools that can be utilized to discover and treat an exploited system.
This type of exploit points out the need for a tiered security policy. In this case sound physical security would preclude a machine being hacked by this mechanism. But if you don't know that your system has been physically protected 24/7… You may be a victim.
