Brief Description 

    

MS07-003 is not categorized as virus, worm, Trojan or backdoor. It is a group of critical vulnerabilities in several versions of Outlook, which allows arbitrary code to be remotely executed in the vulnerable computer.

The affected versions are:

  • Office 2003: Outlook 2003.
  • Office XP: Outlook 2002.
  • Office 2000: Outlook 2000.

If exploited successfully, MS07-003 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. On the other hand, one of the vulnerabilities allows denial of service attacks to be launched, which could cause the affected system to stop responding.

This vulnerability is usually exploited by sending a message that contains a specially crafted file via email to a user who connects to a POP, IMAP or HTTP sever to retrieve the message.

Attacks can be launched across the Internet, but a firewall could be used in order to prevent those attacks.

 

If you have any of the vulnerable versions of Outlook, it is recommendable to download and apply the security patch for this vulnerability. Click here to access the web page for downloading the patch.
