Synopsis
========
A Denial of Service vulnerability has been discovered in Net-SNMP when
processing GETBULK requests.
Background
==========
Net-SNMP is a collection of tools for generating and retrieving SNMP
data.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/net-snmp < 5.4.1-r1 >= 5.4.1-r1
Description
===========
The SNMP agent (snmpd) does not properly handle GETBULK requests with
an overly large "max-repetitions" field.
Impact
======
A remote unauthenticated attacker could send a specially crafted SNMP
request to the vulnerable application, possibly resulting in a high CPU
and memory consumption.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Net-SNMP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.4.1-r1"
References
==========
