This bug talks about the kerberized version of telnet server. # matchpathcon /usr/kerberos/sbin/telnetd /usr/kerberos/sbin/telnetd system_u:object_r:telnetd_exec_t:s0 # rpm -qf /usr/kerberos/sbin/telnetd krb5-appl-servers-1.0.3-7.el7.x86_64 # I believe that the fix will also solve the same problem of the original telnet server, because the files are labelled similarly. # matchpathcon /usr/sbin/in.telnetd /usr/sbin/in.telnetd system_u:object_r:telnetd_exec_t:s0 # rpm -qf /usr/sbin/in.telnetd telnet-server-0.17-57.el7.x86_64 #
This looks like a labeling problem. What is /usr/kerberos/sbin/telnetd labeled?
# ls -Z /usr/kerberos/sbin/telnetd -rwxr-xr-x. root root system_u:object_r:telnetd_exec_t:s0 /usr/kerberos/sbin/telnetd #
Actually the problem with all these bugs is we miss init domain for these inetd domain.
You are right. So these domains all have to be made init daemons.
