Ulf Harnhammar notices that that trackballs follows symlinks when running as
gid games. It writes to files such as $HOME/.trackballs/[USERNAME].gmr and
$HOME/.trackballs/settings without checking if they are symlinks somewhere
else. This can be abused for overwriting or creating files wherever the games
group is allowed to do so.
For the testing distribution (etch) this is fixed in version 1.1.1-0.0etch1
For the unstable distribution (sid) this is fixed in version 1.1.1-1
This upgrade is recommended if you use trackballs.
