DESCRIPTION:
Kevin Finisterre has reported a vulnerability in GpsDrive, which can
be exploited by malicious people to cause a DoS (Denial of Service)
and potentially to compromise a vulnerable system.

The vulnerability is caused due to a format string error in the
"dg_echo()" function in "friendsd.c" when displaying received GPS
position data. This can potentially be exploited to execute arbitrary
code via a specially crafted UDP packet.

Successful exploitation requires the ability to send UDP packets to
port 50123/udp.

The vulnerability affects version 2.09. Other versions may also be
affected.

SOLUTION:
Restrict use to trusted networks only.
