Bug 540345

Summary:

SELinux is preventing /usr/lib64/chromium-browser/chrome-sandbox "open" access
on /proc.

Detailed Description:

[chrome-sandbox has a permissive type (chrome_sandbox_t). This access was not
denied.]

SELinux denied access requested by chrome-sandbox. It is not expected that this
access is required by chrome-sandbox 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.
