Description of problem: SELinux prevents flex application in a firefox browser to connect to a TCP port in the network Version-Release number of selected component (if applicable): nspluginwrapper-1.1.2-4.fc10 selinux-policy-3.5.13-18.fc10 How reproducible: When the flex application is downloaded into the Firefox browser and when the flex application is trying to connect to the port xx on a network server. Steps to Reproduce: 1. Download swf application with firefox 2. Application tries to connect to port xx 3. SELinux prevents the npviewer.bin to allow this connection Actual results: Expected results: Additional info: Trying to allow access using: semanage port -a -t PORT_TYPE -p PROTOCOL xx Seems not to help. Also: setsebool -P allow_unconfined_nsplugin_transition 0 Seems not to help either... - - - - - - - - - SELinux Additional Information: Target Context: system_u:object_r:port_t:s0 Target Objects: None [ tcp_socket ] Source: npviewer.bin Source Path: /usr/lib/nspluginwrapper/npviewer.binPort: xx Host: Source RPM Packages: nspluginwrapper-1.1.2-4.fc10 Target RPM Packages: Policy RPM: selinux-policy-3.5.13-18.fc10 Selinux Enabled: True Policy Type: targeted MLS Enabled: True Enforcing Mode: Enforcing Plugin Name: connect_ports Raw Audit Messages :node=xxxx type=AVC msg=audit(1228239276.420:44): avc: denied { name_connect } for pid=3611 comm="npviewer.bin" dest=xxxx scontext=unconfined_u:unconfined_r:nsplugin_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket node=xxxx type=SYSCALL msg=audit(1228239276.420:44): arch=40000003 syscall=102 success=no exit=-13 a0=3 a1=43b82c0 a2=18a5924 a3=0 items=0 ppid=3592 pid=3611 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="npviewer.bin" exe="/usr/lib/nspluginwrapper/npviewer.bin" subj=unconfined_u:unconfined_r:nsplugin_t:s0 key=(null)
Turn off the plugin transition # setsebool -P allow_unconfined_nsplugin_transition 0 Then restart firefox, it should work then. I am changing the default since this is happening to too many people. Fixed in selinux-policy-3.5.13-31.fc10

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Closing as current release
