CVE-2020-6581 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nagios-nrpe package and not the nagios-nrpe package as distributed by Ubuntu.
Nagios NRPE 3.2.1 has Insufficient Filtering because, for example, nasty_metachars interprets \n as the character \ and the character n (not as the \n newline sequence). This can cause command injection.
