gpm-root initgroups()

Hello!

As reported before, the "gpm-root" daemon in gpm-1.19.0 and earlier lets
the user execute any command with uid=0. gpm-1.19.1 fixed half of the
security hole by calling setuid() and setgid() at the right place but not
calling initgruops().

gpm-1.19.2 is out there, which calls initgroups() correctly, fully
fixing this security hole. Therefore anyone running gpm-root is highly
recommended to upgrade to gpm-1.19.2 or apply its setuid(), setgid() and
initgruops() releated patches.

Best regards
