Description Nils Philippsen 2009-11-17 13:44:13 UTC
Summary:

SELinux is preventing /usr/sbin/uuxqt "execute" access on /bin/bash.

Detailed Description:

SELinux denied access requested by uuxqt. It is not expected that this access is
required by uuxqt 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.

You can add these rules for now using

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