Gentoo Linux Security Advisory

Title: X2Go Server: Arbitrary code execution (GLSA 201310-19)
Severity: high
Exploitable: remote
Date: October 28, 2013
Bug(s): #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: net-misc/x2goserver
Vulnerable: < 4.0.0.2
Unaffected: >= 4.0.0.2
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-misc/x2goserver-4.0.0.2"
