Description of problem: The BBC iPlayer Desktop Application for Linux can auto-update itself, however it is prevented from doing so by selinux, and generates an avc message. It does however ask for the root password before doing so and should be seen as reasonably secure. You can find iPlayer on the BBC website http://bbc.co.uk/iplayer Version-Release number of selected component (if applicable): Running Fedora 11 updated as of 13/08/09. How reproducible: Every time. Additional info: AVC message from setroubleshoot (great program by the way) below - Summary: SELinux is preventing rpm (unconfined_execmem_t) "transition" rpm_script_t. Detailed Description: SELinux denied access requested by rpm. It is not expected that this access is required by rpm 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: 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.

Why is rpm running as unconfined_execmem_t?
I'm afraid I can't answer your question, I am clueless when it comes to selinux. I have never altered what mode selinux is in (haven't found it really necessary this release). I have found a workaround to this by downloading the update itself (.air) and executing that in my home folder. Thanks.
I think what is happening is you have firefox running as unconfined_execmem_t and when it tried to execute rpm to install a package, it failed. Were you running as root?
I wasn't running my session as root, however the update process pops up an Adobe Air window that asks for the root password to continue the upgrade of iPlayer, this is perhaps the equivalent. If there's any other questions or logs you need, don't hesitate to ask. Thanks.
Jonathan the BBC will not let me run this from the states. I just wish I new what app is running this for you. Miroslav, add unconfined_execmem_trpm_transition_script(unconfined_execmem_t) to unconfineduser.te
Sorry I don't understand your last part of Comment #5, are those instructions for me to run? If there's anything you want me to do, to help you troubleshoot this, just send me the instructions through the bug report and I'll run them and give you the results - it's in everyone's interest. Thanks for responding so quickly all the time, I've come across a number of other problems with selinux that I'd rather report as bugs to hopefully be fixed, in the hope of a smoother future. I'll report those separately obviously.
Fixed in selinux-policy-3.6.12-82.fc11
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 '11'. 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 11'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 11 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
