Microsoft Windows is prone to a remote code-execution vulnerability. An attacker can exploit this issue by tricking an unsuspecting victim into viewing a malformed file. Successful exploits can allow attackers to execute arbitrary code within the privileges of the user running the affected application. Note: This issue can also be exploited by embedding other file types such as Python ('.py') or '.jar' files, if the correct interpreter is installed on the vulnerable computer.
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged 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.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
