Description Jerry Purvis 2009-12-03 01:47:29 UTC
Summary:

SELinux is preventing /usr/bin/abrt-pyhook-helper access to a leaked
/dev/snd/controlC0 file descriptor.

Detailed Description:

[abrt-pyhook-hel has a permissive type (abrt_helper_t). This access was not
denied.]

SELinux denied access requested by the abrt-pyhook-hel command. It looks like
this is either a leaked descriptor or abrt-pyhook-hel output was redirected to a
file it is not allowed to access. Leaks usually can be ignored since SELinux is
just closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the /dev/snd/controlC0. You should generate a bugzilla on
selinux-policy, and it will get routed to the appropriate package. You can
safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)

Comment 1 Daniel Walsh 2009-12-03 14:31:01 UTC
You can ignore these. Selinux is just closing leaked file descriptors.

Fixed in selinux-policy-3.6.32-53.fc12
