high Nessus Plugin ID 100274

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Infinite loop due to incorrect interaction of parse_packet() and parse_part_sign_sha256() functions :

Collectd contains an infinite loop due to how the parse_packet() and parse_part_sign_sha256() functions interact. If an instance of collectd is configured with 'SecurityLevel None' and with empty 'AuthFile' options an attacker can send crafted UDP packets that trigger the infinite loop, causing a denial of service.

Run 'yum update collectd' to update your system.
