1) Denial of service (CVE-ID: CVE-2017-16820)
CWE-ID: CWE-415 - Double Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists due to the csnmp_read_table function in the snmp.c code in the SNMP plug-in of the collectd daemon. A remote attacker can send specially crafted input to the target system, trigger a double-free memory condition and cause the collected daemon to crash.
