During a software upgrade driven by pup, I had multiple AVC denies.  These
included denies on running restorecon, so I suspect that the system state became

The following packages caused alerts

Comment 4 Daniel Walsh 2007-04-16 14:18:36 UTC
These are leaked file descriptors by pup/rpm, or what ever tool you were using
to update.  Luckily they do not effect the update.  Any app that execs other
apps should make sure that all file descriptors are closed before the exec. 
SELinux checks all open file descriptors for access before running a confined
app, which triggers these avc messages.  After the denial, the kernel closes the
file descriptors and continues the application.

Changing this bug to pirut

Comment 5 Jeremy Katz 2007-04-16 14:39:54 UTC
Do you just see this with pup or do you also see it with just using yum?  I
can't think of anything which would be pup specific here.

Comment 6 Michael De La Rue 2007-05-27 13:09:48 UTC
It was a one off thing and hasn't repeated.  I have run yum directly and have
never seen such a thing again.
