A vulnerability in Net-SNMP could lead to a Denial of Service.
Net-SNMP is a collection of tools for generating and retrieving SNMP data.
Oscar Mira-Sanchez reported an integer overflow in the netsnmp_create_subtree_cache() function in agent/snmp_agent.c when processing GETBULK requests.
A remote attacker could send a specially crafted request to crash the SNMP server. NOTE: The attacker needs to know the community string to exploit this vulnerability.
Restrict access to trusted entities only.
All Net-SNMP users should upgrade to the latest version:
