Description Göran Uddeborg 2011-10-07 20:02:33 UTC

Description of problem:
Setroubleshoot sent me a report that a process in the gpg_t domain had tried to read a file with the mail_spool_t type and been denied.  This happens for a user_u user.  (I have __default__ mapped to user_u, and a few selected users mapped to unconfined_u in my /etc/selinux/targeted/seusers)

Most likely, the user had logged in and read his mail using mutt, and mutt had tried to verify a signature in one of the mails.  This seems like something that would make sense to allow.  Is it intentional it is prohibited, or is it a bug that should be fixed?

Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.10.0-38.fc16.noarch

I forgot, I should of course have included the actual AVC:
