Description Gilboa Davara 2009-04-08 07:29:35 UTC
Trying to send fax - getting AVC denials.
Seems to be new. (hp-sendfax worked just fine since the last SELinux fix https://bugzilla.redhat.com/show_bug.cgi?id=476183)

$ sealert -l 371f6111-9f1a-46d9-aaaf-46246ad4e49c

Summary:

SELinux is preventing the python from using potentially mislabeled files
(hpfax-pipe-60).                                                        

Detailed Description:

SELinux has denied python access to potentially mislabeled file(s)
(hpfax-pipe-60). This means that SELinux will not allow python to use these
files. It is common for users to edit files in their home directory or tmp 
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.                                                              

Allowing Access:

If you want python to access this files, you need to relabel them using
restorecon -v 'hpfax-pipe-60'. You might want to relabel the entire directory
using restorecon -R -v '<Unknown>'.

Comment 6 Bug Zapper 2009-11-18 11:42:32 UTC
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  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bug reports from releases that are no longer maintained.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 '10'.

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 10'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 10 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

Comment 7 Daniel Walsh 2009-11-18 13:04:48 UTC
Closing as closed in the current release.
