Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU6706
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7401
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause denial of service (DoS) conditions.
The vulnerability exists due to improper input validation when processing UDP requests within the parse_packet() and parse_part_sign_sha256() functions in network.c.A remote attacker can send specially crafted UDP packets to vulnerable instance of collectd and trigger infinite loop.
Successful exploitation of the vulnerability may allow an attacker to cause denial of service (DoS) conditions, but requires that collectd is configured with "SecurityLevel None" and with empty "AuthFile" options.

2) Denial of service
EUVDB-ID: #VU10565
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-16820
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe 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.
