Microsoft Office Publisher is prone to a remote code-execution vulnerability. An attacker can exploit this issue by enticing an unsuspecting victim to open a maliciously crafted Publisher file. Successful exploits may allow attackers to execute arbitrary code with privileges of the user running the application. This may facilitate a compromise of vulnerable computers.

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.
Users should never accept files from untrusted or unknown sources, because they may be malicious in nature. Avoid opening email attachments from unknown or questionable sources.
Do not follow links provided by unknown or untrusted sources.
Users should avoid websites of questionable integrity. Never follow links supplied by unknown or untrusted sources.
Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as non-executable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploit attempts of memory-corruption vulnerabilities.
Microsoft released an advisory and fixes to address this issue. Please see the references for more information.
eEye Research is credited with the discovery of this vulnerability.
