Even if there is no patch, there are two font files that can be considered "additional downloads". If the bridgehead is removed, it confuses jhalfs, by making the font files appear on the same footing as the main package.

vulnerabilities, but others of these copies are less-well maintained.

To ensure that any future fixes are applied throughout the whole system,

it is recommended that you first install the released versions of these

to link to them.

If you have downloaded the fonts, unpack them to
