Microsoft Windows SMB Client Transaction Response Remote Stack Buffer Overflow Vulnerability

Risk

High

Date Discovered

April 13, 2010

Description

Microsoft Windows is prone to a remote stack-based buffer-overflow vulnerability. An attacker can exploit this issue to execute code with SYSTEM-level privileges. Failed exploit attempts will likely cause denial-of-service conditions.

Recommendations

Block external access at the network boundary, unless external parties require service.

If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploitation.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include explained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to websites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.

Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
