Product Background
===================
Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring the health and welfare of network equipment (eg. routers), computer equipment and even devices like UPSs. Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6.

Problem Background - Impact
===================
snmp_api.c in snmpd in Net-SNMP 5.2.x before 5.2.2, 5.1.x before 5.1.3, and 5.0.x before 5.0.10.2, when running in master agentx mode, allows remote attackers to cause a denial of service (crash) by causing a particular TCP disconnect, which triggers a free of an incorrect variable, a different vulnerability than CVE-2005-2177.

Package: net-snmp
Repo: current
Group: network
Unsafe: < 5.2.2
Safe: >= 5.2.2

Package Fix
