<bug>198346</bug>
<access>remote</access>
<affected>
<package name="net-analyzer/net-snmp" auto="yes" arch="*">
<unaffected range="ge">5.4.1-r1</unaffected>
<vulnerable range="lt">5.4.1-r1</vulnerable>
</package>
</affected>
<background>
<p>
Net-SNMP is a collection of tools for generating and retrieving SNMP
data.
</p>
</background>
<description>
<p>
The SNMP agent (snmpd) does not properly handle GETBULK requests with
an overly large "max-repetitions" field.
</p>
</description>
<impact type="normal">
<p>
A remote unauthenticated attacker could send a specially crafted SNMP
request to the vulnerable application, possibly resulting in a high CPU
and memory consumption.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Net-SNMP users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.4.1-r1"</code>
</resolution>
