Microsoft Windows CVE-2011-0657 DNS Resolution Remote Code Execution Vulnerability

Description

Microsoft Windows is prone to a remote code-execution vulnerability. Successful exploits can allow attackers to execute arbitrary code within the context of the NetworkService account. Successfully exploiting this issue will result in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.

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 successful exploits.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
