"Two different problems were found in libgtop-daemon :

  - The laboratory intexxia found a format string problem in
    the logging code from libgtop_daemon. There were two
    logging functions which are called when authorizing a
    client which could be exploited by a remote user.
  - Flavio Veloso found a buffer overflow in the function
    that authorizes clients.

Since libgtop_daemon runs as user nobody, both bugs could be used to
gain access as the nobody user to a system running libgtop_daemon.


Both problems have been fixed in version 1.0.6-1.1 and we recommend
you upgrade your libgtop-daemon package immediately."
