| Business Impact: |
An unspecified, and currently unpatched, Microsoft Office PowerPoint vulnerability is receiving targeted exploitation in the wild. Successful attacks will lead to code execution and malware installation.
While some customers may be able to react by blocking email with PowerPoint attachments through traditional email filtering means, this may not be feasible for everyone. In this case, customers should enable protection technologies like the Proventia IPS signatures for this issue and deploy patches as soon as they are available. |
