  <synopsis>

    a local attacker to execute arbitrary code.

    <package name="app-misc/tomboy" auto="yes" arch="*">

    <p>
    Tomboy is a GTK-based desktop note-taking application written in C# and
    the Mono C#.
    </p>
  </background>
  <description>
    <p>
    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.
    </p>
  </description>
  <impact type="normal">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    Do not run Tomboy from an untrusted working directory.
    </p>
  </workaround>
  <resolution>
    <p>
    All Tomboy users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-misc/tomboy-0.8.1-r1&quot;</code>
  </resolution>
