MS07-065 is not categorized as virus, worm, Trojan or backdoor. It is an important vulnerability in the Message Queuing Service on Windows XP/2000 computers, which allows arbitrary code to be remotely executed in the vulnerable computer.
Message Queuing technology provides guaranteed message delivery, efficient routing, security and priority-based messaging.
If exploited successfully, MS07-065 allows hackers to gain remote control of the affected computer with the same privileges as the logged on user. 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.
To exploit this vulnerability locally an attacker would have to log on to the system and to exploit it remotely, an attacker would have to send specially crafted packets to the Message Queuing Service.
