PocketMine-MP invalid skin geometry JSON data leading to server crash
Impact
pocketmine\entity\Skin doesn't correctly handle errors produced by adhocore/json-comment, which throws RuntimeException rather than returning false as PocketMine-MP expects.
This leads to a server crash if the skin geometry data is invalid for some reason (e.g. a syntax error).
Patches
c9626c610b8f6810c8c987559c9197b2a291f0bb
Workarounds
A plugin could handle LoginPacket and PlayerSkinPacket to verify the skin geometry data can be parsed correctly, so that the error condition in the core code is never reached.
