CVE-2022-44792 Net-SNMP 5.8 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker to crash the instance.

CVE-2022-44792 Net-SNMP 5.8 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker to crash the instance.

This issue does not affect versions of Net-SNMP before 5.8.5. Upgrade to a more recent version. This issue has been assigned CVE-2017-16758. A remote attacker may be able to exploit this vulnerability to crash a Net-SNMP instance via a crafted UDP packet, resulting in Denial of Service. CVE-2017-14927 The ipv6_find_1stfragopt function in mib-ipv6.c in Net-SNMP 5.8 through 5.9.3 has a buffer overflow. It is possible to create a specially crafted SNMP request that could cause the SNMP daemon to crash when it processes the request. This could be exploited in a DoS attack.

CVE-2017-14928 In Net-SNMP 5.8 through 5.9.3, the snmp_parse_addr function in snmp.c has a buffer overflow. It is possible to create a specially crafted SNMP request that could cause the SNMP daemon to crash when it processes the request. This could be exploited in a DoS attack.

CVE-2017-14929 In Net-SNMP 5.8 through 5.9.3, the snmp_get_v1_community function in mib-v1.c has a buffer overflow. It is possible to create a specially crafted SNMP request that could cause the SNMP daemon to crash when it processes the request

SNMP Overview

SNMP, also known as Simple Network Management Protocol, is a network management protocol for use in monitoring and managing networks of almost any size. It was developed as an easier way to monitor and manage network devices such as routers. SNMP provides a simple text-based user interface that can be used by humans or automated scripts to query and configure the state of devices on the network.
All modern operating systems contain built-in support for SNMP. This allows them to act as SNMP agents which allow an outside system like a "Super Server" application to monitor and configure multiple devices on the local machine or across the entire network.
