write common file types and handle structured formats that provide
file-system-in-a-file semantics.

<description>
<p>
"infamous41md" has discovered that the "ole_init_info" function may
allocate too little memory for storing the contents of an OLE document,
resulting in a heap buffer overflow.
</p>
</description>
<impact type="normal">
<p>
An attacker could entice a user to open a specially crafted OLE
document, and possibly execute arbitrary code with the rights of the
user opening the document.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libgsf users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=gnome-extra/libgsf-1.14.2&quot;</code>
</resolution>
