A security vulnerability in the 3rd party library XPDF (only used in the PDF import extension), related to PDF document processing, may allow a remote unprivileged user to execute arbitrary code on the system with the privileges of a local user running OpenOffice.org, if the local user opens a crafted PDF document provided by the remote user.
There are no predictable symptoms that would indicate this issue has occurred.
To workaround the described issue, do not load documents from untrusted sources.
This issue is addressed in the following release: PDF Import Extension 1.0.4
