Does this matter?
Lower severity and a low EPSS score (1.15%). Track it; it rarely justifies an emergency change on its own.
Description
BlockHosts before 2.0.4 does not properly parse (1) sshd and (2) vsftpd log files, which allows remote attackers to add arbitrary deny entries to the /etc/hosts.allow file and cause a denial of service by adding arbitrary IP addresses to a daemon log file, as demonstrated by connecting through ssh with a client protocol version identification containing an IP address string, or connecting through ftp with a username containing an IP address string, different vectors than CVE-2007-2765.
