CVE-2019-17561
Summary
-------
The "Apache NetBeans" autoupdate system does not fully validate
code signatures.
Versions Affected:

downloads by checking signatures and/or comparing checksums
from trusted sources
- Update to NetBeans 11.3 by downloading the release, verifying the
signature and manually installing it
