Description Joe Zeff 2009-01-28 02:48:47 EST
Found in SeLinux troubleshooter:


SELinux is preventing sshd (sshd_t) "search" crond_t.

Detailed Description:

SELinux denied access requested by sshd. It is not expected that this access is
required by sshd and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Comment 1 Paul Wouters 2009-01-28 12:34:20 EST
re-assigned to the right package.
Comment 2 Daniel Walsh 2009-01-30 08:23:03 EST
This is a bug in the kernel and can be safely ignored.


Rawhide and maybe F10 policy have the following in domain.te

	allow domain domain:key { link search };
Which will get rid of this avc.
Comment 3 Miroslav Grepl 2009-01-30 08:32:58 EST
Yes, F10 has this rule. I'll add it to F9 policy.

Comment 5 Bug Zapper 2009-06-09 23:31:03 EDT
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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:
