Microsoft Word Bulleted List Handling Remote Memory Corruption Vulnerability

Risk

High

Date Discovered

June 17, 2008

Description

Microsoft Word is prone to a remote memory-corruption vulnerability. An attacker could exploit this issue by enticing a victim to open and interact with malicious Word files. Successfully exploiting this issue will corrupt memory and crash the application. Given the nature of this issue, attackers may also be able to execute arbitrary code in the context of the currently logged-in user.

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.
