Date:	10/28/2013
Bugs:	#472582
ID:	201310-19

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

Package	Vulnerable	Unaffected	Architecture(s)
net-misc/x2goserver	< 4.0.0.2	>= 4.0.0.2	All supported architectures

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

A remote attacker may be able to execute arbitrary code with the privileges of the user running the server process.

Workaround

There is no known workaround at this time.

Resolution

All X2Go Server users should upgrade to the latest version:

      # emerge --ask --oneshot --verbose ">=net-misc/x2goserver-4.0.0.2"
