Apache OpenOffice: Stack overflow in CFF hint handling

Summary

An uncontrolled memory access in the PDF export code of Apache OpenOffice versions through 4.1.16 allows a crafted CFF font to cause a stack overflow problem, causing program crash or memory corruption, or even running other code. Users are recommended to upgrade to version 4.1.17, which fixes this issue.

Remediation

1. Inventory every Apache Software Foundation Apache OpenOffice deployment, including staging.
2. No fixed version appears in the public sources yet. Check the references below and the vendor directly.
