Description of problem: SELinux is preventing gtk-gnash (nsplugin_t) "getattr" to /var/run/pcscd.pub (pcscd_var_run_t). Version-Release number of selected component (if applicable): selinux-policy-3.5.13-18.fc10.noarch How reproducible: Once. Steps to Reproduce: 1. Install gnash-mozilla 2. Run firefox 3. Surf to site using flash Actual results: avc denial Expected results: no denial Additional info: Summary: SELinux is preventing gtk-gnash (nsplugin_t) "getattr" to /var/run/pcscd.pub (pcscd_var_run_t). Detailed Description: SELinux denied access requested by gtk-gnash. It is not expected that this access is required by gtk-gnash and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for /var/run/pcscd.pub, restorecon -v '/var/run/pcscd.pub' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

The library should be closing all open file descriptors on exec from firefox, this would allow us to get a handle on what the plugin is actually trying to do.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
When the library opens /var/run/pcscd.pub it should execute fcntl(fd, F_SETFD, FD_CLOEXEC)
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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
