buffer overflow.

<impact type="normal">
<p>A remote attacker could entice a user to open a specially crafted BDF
file using FontForge font editor, possibly resulting in the remote
execution of arbitrary code with the privileges of the FontForge process,
or a Denial of Service (application crash).
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All FontForge users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=media-gfx/fontforge-20110222-r1"
</code>
<p>NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 12, 2011. It is likely that your system is
