SELinux is preventing /sbin/consoletype "read" access on /root/.vnc/(removed):2.log.

Detailed Description:

[consoletype has a permissive type (consoletype_t). This access was not denied.]

SELinux denied access requested by consoletype. It is not expected that this
access is required by consoletype 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Miroslav Grepl 2010-12-20 13:18:11 UTC
This one looks like a leak descriptor. We allow consoletype to append file with admin_home_t label.

You can dontaudit it using

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

Which vnc tool were you using when this happened?
