<background>
<p>LZO is an extremely fast compression and decompression library</p>
</background>
<description>
<p>LZO is vulnerable to an integer overflow condition in the
“lzo1x_decompress_safe” function which could result in a possible
buffer overrun when processing maliciously crafted compressed input data.
</p>

<impact type="normal">
<p>A remote attacker could send specially crafted compressed input data
possibly resulting in a Denial of Service condition or arbitrary code
execution.

</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All LZO users should upgrade to the latest version:</p>

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/lzo-2.08"
</code>
