| Description: | The tcp_wrappers package provides small daemon programs which can monitor and filter incoming requests for systat, finger, FTP, telnet, rlogin, rsh, exec, tftp, talk and other network services. It also contains the libwrap library that adds the same filtering capabilities to programs linked against it, like sshd and more.
This update brings the following changes:
localhost and localhost.localdomain are treated as being equivalent when comparing the client hostname and the list of allowed/denied hostnames.
the hosts_ctl function uses the address parameter to get the ip address and resolve it to symbolic hostname, if not given.
the behavior of signal handling when the "spawn" option is used has been changed to be transparent to the application using the library.
These fixes correct the behavior of certain applications, including net-snmp and vsftpd.
Users should upgrade to this updated package, which resolves these issues.
