Synopsis
========

Tomboy doesn't properly handle environment variables, potentially
allowing a local attacker to execute arbitrary code.

Background
==========

Tomboy is a GTK-based desktop note-taking application written in C# and
the Mono C#.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-misc/tomboy < 0.8.1-r1 >= 0.8.1-r1

Description
===========

Jan Oravec reported that the "/usr/bin/tomboy" script sets the
"LD_LIBRARY_PATH" environment variable incorrectly, which might result
in the current working directory (.) to be included when searching for
dynamically linked libraries of the Mono Runtime application.

Impact
======

A local attacker could entice a user into running Tomboy in a directory
containing a specially crafted library file to execute arbitrary code
with the privileges of the user running Tomboy.

Workaround
==========

Do not run Tomboy from an untrusted working directory.

Resolution
==========

All Tomboy users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/tomboy-0.8.1-r1"
