Summary: SELinux is preventing /usr/lib64/chromium-browser/chrome-sandbox "read" 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.

Created attachment 372699 [details] audit.log entries for chrome's avc flurry chromium is being a bad boy and playing around in /proc
This bug should probably be filed against chromium for mucking about in /proc. What is it doing down there anyway?
Looks like the chromium sandbox is doing the equiv of a ps command. I will dontaudit this to prevent it. Not sure if this is a chrome-sandbox bug or not. But a sandbox should definitely not be able to list the running process on a system. Fixed in selinux-policy-3.6.32-48.fc12.noarch
