Description:	Summary: The remote host is missing an update for the 'fail2ban' package(s) announced via the MGASA-2021-0464 advisory. Vulnerability Insight: fail2ban is a daemon to ban hosts that cause multiple authentication errors. In versions 0.9.7 and prior, 0.10.0 through 0.10.6, and 0.11.0 through 0.11.2, there is a vulnerability that leads to possible remote code execution in the mailing action mail-whois.
