Welcome to the Virus Encyclopedia of Panda Security.
MS06-018 is not categorized as virus, worm, Trojan or backdoor. It is a group of moderate vulnerabilities in the MSDTC (Microsoft Distributed Transaction Coordinator), on Windows 2003/XP/2000 computers, which allows DoS (Denial of Service) attacks to be launched against the vulnerable systems.
The two addressed vulnerabilities refer to the MSDTC, and are due to an unchecked buffer in this component.
If exploited successfully, MS06-018 allows hackers to cause the computer to stop responding.
MS06-018 is exploited by creating a specially crafted packet that is sent to the vulnerable computer. Although it is possible to launch this type of attacks across the Internet, a firewall could be used in order to prevent those attacks.
If you have a Windows 2003/XP/2000 computer, it is recommendable to download and apply the security patch for this vulnerability. Click here to access the web page for downloading the patch.
