Microsoft Windows Server Driver Mailslot Remote Heap Buffer Overflow Vulnerability

Risk
High

Date Discovered
7/11/2006 12:00:00 AM

Description
Microsoft Windows Server driver is susceptible to a remote heap buffer-overflow vulnerability. This issue is due to a failure of the software to properly bounds check user-supplied input prior to copying it to an insufficiently-sized memory buffer. Exploiting this issue allows anonymous, remote attackers to execute arbitrary machine code in the context of the affected driver. This facilitates the complete compromise of affected computers. Microsoft Windows XP SP2 and Microsoft Windows Server 2003 SP1 are not vulnerable to this issue in their default configuration.

Recommendations
Block external access at the network boundary, unless external parties require service.
Allow only trusted hosts and networks to connect to TCP port 445 on computers running the affected software. This will limit the potential for remote attackers to exploit this issue.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Network intrusion detection systems should be deployed to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Implement multiple redundant layers of security.
An attacker's ability to exploit this vulnerability to execute arbitrary code may be hindered through the use of various memory protection schemes. Where possible, implement the use of non-executable and randomly mapped memory segments.
