<description>
<p>
Tavis Ormandy of the Google Security Team discovered several heap and
stack buffer overflows and other flaws in libTIFF. The affected parts
include the TIFFFetchShortPair(), TIFFScanLineSize() and
EstimateStripByteCounts() functions, and the PixarLog and NeXT RLE
decoders.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted TIFF
file, resulting in the possible execution of arbitrary code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libTIFF users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/tiff-3.8.2-r2&quot;</code>
</resolution>
