Description jeff 2009-12-28 20:11:26 UTC
Summary:

SELinux is preventing /usr/sbin/in.telnetd "setattr" access on 0.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by in.telnetd. It is not expected that this
access is required by in.telnetd 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) Please file a bug
report.

Comment 1 Daniel Walsh 2009-12-29 22:46:33 UTC

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
