Apache OpenOffice: code execution
Fix: upgrade to 95923fd437e06edd38a4f0e139a27c755a6f3ba6 or later (2 fixed versions below)
A code execution issue in the Java integration in Apache OpenOffice v4.1.16 and earlier allows a crafted untrusted document to trigger executing arbitrary (even remote) code when opened by the user.
This issue is expected to be fixed in version 4.1.17, which is in the release candidate phase.
Until then, users can mitigate this issue by disabling Java runtime integration in the Preferences dialog. This prevents the attack. If this is not possible, or as an extra precaution, you can avoid opening open untrusted files entirely. Once 4.1.17 is released, upgrade to that version to fix the issue.
