Summary

net-snmp security update

Details

Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6. The suite includes:

    - An extensible agent for responding to SNMP queries including built-in support for a wide range of MIB information modules
    - Command-line applications to retrieve and manipulate information from SNMP-capable devices
    - A daemon application for receiving SNMP notifications
    - A library for developing new SNMP applications, with C and Perl APIs
    - A graphical MIB browser.

Security Fix(es):

handle_ipv6IpForwarding in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.4.3 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.(CVE-2022-44793)

handle_ipDefaultTTL in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.8 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker (who has write access) to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.(CVE-2022-44792)

Severity

6.5 (Medium)
