Description Daniel Walsh 2004-10-01 13:53:02 EDT
Description of problem:

+allow $1_lpr_t $1_mozilla_t:tcp_socket { read write };
+allow $1_lpr_t $1_mozilla_t:unix_stream_socket { read write };

SELinux wants to generate the above commands when execing lpr from
within firefox.  This is caused because some file descriptors are not
being closed on the exec.

fcntl(fd,   F_SETFD, FD_CLOEXEC)

This is a potential security hole in that the spawning process would
be able to read/write from these open sockets.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Bring up a pdf in the viewer and attempt to print.
Actual results:
SELinux denial messages

Expected results:
No SELinux denial messages.
