Multiple Microsoft Products CVE-2013-3906 Remote Code Execution Vulnerability

Description

Multiple Microsoft products including Microsoft Windows, Microsoft Office, and Microsoft Lync are prone to a remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code in the context of the currently logged-in user, which may lead to a complete compromise of an affected computer.

Recommendations

Run all software as a nonprivileged user with minimal access rights.
To mitigate the impact of a successful exploit, run the affected application as a user with minimal access rights.

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.

Do not accept or execute files from untrusted or unknown sources.
Never accept files from untrusted or unknown sources, because they may be malicious in nature. Avoid opening email attachments from unknown or questionable sources.

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 exploit attempts of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
