Synopsis
========
A path vulnerability in X2Go Server may allow remote execution of
arbitrary code.

Background
==========
X2Go is an open source terminal server project.

Affected packages
=================
-------------------------------------------------------------------

Description

A vulnerability in the setgid wrapper x2gosqlitewrapper.c does not
hardcode an internal path to x2gosqlitewrapper.pl, allowing a remote
attacker to change that path.

Impact

privileges of the user running the server process.

Workaround
