Debian Security Advisory DSA-098-1                   security@debian.org 
http://www.debian.org/security/                         Wichert Akkerman

Package        : libgtop
Problem type   : remote nobody exploit
Debian-specific: no

Two different problems where 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.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

Debian GNU/Linux 2.2 alias potato
