Alert file from setroubleshoot
Following setroubleshoot's advice (running chcon -t unconfined_execmem_exec_t '/usr/lib64/firefox-3.0.1/firefox') seems to fix the issue although I definitely don't like the thought of my browser being able to execute from the stack. Moreover, setroubleshoot's description claims that an executable stack should never be necessary. Unfortunately, I wasn't able to find any libraries with the execstack flag set so I wasn't able to try clearing it. Does swfdec really need an execstack. yet another execmem programming problem highlighted by selinux. Seems we've found a few of these lately... The problem here is that flash plugin requires execmem, a better solution is to install nspluginwrapper and run flash in a separate process that is confined. After you install the plugin wrapper you should relabel your home directory. restorecon -R -v ~/ You should really report a bug to adobe so we can get them to fix it or tell us why they can not. Sadly I have to turn off this checking in selinux-policy-3.5.13-10.fc10 You can turn it off by executing setsebool -P allow_execstack 1 Re-opening to Modified until the build is actually tagged for rawhide. Which it is now. |
