<p>
iDefense Labs reported that the TIFF parsing code uses untrusted values
to calculate buffer sizes, which can lead to an integer overflow
resulting in heap-based buffer overflow.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted
document, possibly leading to execution of arbitrary code with the
privileges of the user running OpenOffice.org.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
