Synopsis
========

A vulnerability in Tomboy could result in privilege escalation.

Background
==========

Tomboy is a desktop note-taking application.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-misc/tomboy             < 1.4.2-r1               >= 1.4.2-r1

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

Tomboy places a zero-length directory name in the LD_LIBRARY_PATH,
which might result in the current working directory (.) to be included
when searching for dynamically linked libraries.

NOTE: This vulnerability exists due to an incomplete fix for
CVE-2005-4790 (GLSA 200711-12).

Impact
======

A local attacker could gain escalated privileges via a specially
crafted shared library.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Tomboy users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-misc/tomboy-1.4.2-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since March 02, 2011. It is likely that your system is
already no longer affected by this issue.
