Overview
Foxit Reader contains a vulnerability that may allow an attacker to execute arbitrary commands without requiring user interaction.
Description
Foxit Reader is software designed to view Portable Document Format (PDF) files. The Adobe PDF Reference supports a "Launch action" that "... launches an application or opens or prints a document." Foxit Reader uses the ShellExecute function to handle PDFs that use a Launch action. In some cases, Foxit Reader will not prompt the user before an application is launched with a Launch action. It is also reported that the Launch Action can be used to launch an executable that is included in the PDF document, which results in arbitrary code execution. |
Impact
By convincing a user to open a PDF document, e.g. by visiting a website, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. |
Solution
Apply an update This issue is addressed in Foxit Reader 3.2.1.0401. This update will cause Foxit Reader to prompt the user before using a Launch Action. |
