MS09-065 is not categorized as virus, worm, Trojan or backdoor. It is a group of critical vulnerabilities in the Windows Kernel-Mode Drivers on Windows Server 2008/Vista/2003/XP/2000 computers, which allows arbitrary code to be remotely executed and local privilege escalation to be gained in the vulnerable computer. The kernel is the core of the operating system and provides basic services for all other parts of the operating system. If exploited successfully, MS09-065 allows hackers to gain remote control of the affected computer with the same privileges as the logged on user and to gain unauthorized privileges on a computer or network. If this user had administrator rights, the hacker could take complete control of the system: create, modify or delete files, install programs, create new user accounts, etc. MS09-065 is exploited by creating embedded fonts and enticing users to open a website or a document containing them. It can also be exploited by running a specially crafted program in the vulnerable computer. In order to do so, a hacker must be able to log on locally to the system. If you have a Windows Server 2008/Vista/2003/XP/2000 computer, it is recommended to download and apply the security patch for this vulnerability.
