Summary: SELinux is preventing /usr/lib64/chromium-browser/chromium-browser "read" access on /usr/share/X11/fonts/TTF/luxisr.ttf. Detailed Description: [chromium-browse has a permissive type (chrome_sandbox_t). This access was not denied.] SELinux denied access requested by chromium-browse. It is not expected that this access is required by chromium-browse 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.

selinux-policy-3.6.32-46.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/selinux-policy-3.6.32-46.fc12
selinux-policy-3.6.32-46.fc12 has been pushed to the Fedora 12 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update selinux-policy'.

I updated to selinux-policy-3.6.32-46.fc12, but SELinux still shows warnings about Chromium trying to access /proc and dictionaries: SELinux has denied chromium-browse access to potentially mislabeled file(s) (/home/xxxxxx/.config/chromium/Dictionaries/es-ES-1-1.bdic). This means that SELinux will not allow chromium-browse to use these files. It is common for users to edit files in their home directory or tmp directories and then move (mv) them to system directories. The problem is that the files end up with the wrong file context which confined applications are not allowed to access. node=xxxxxxxxxxx type=AVC msg=audit(1259005528.146:1202): avc: denied { read } for pid=15209 comm="chromium-browse" path="/home/xxxxxx/.config/chromium/Dictionaries/es-ES-1-1.bdic" dev=dm-0 ino=7405727 scontext=unconfined_u:unconfined_r:chrome_sandbox_t:s0 tcontext=unconfined_u:object_r:gnome_home_t:s0 tclass=file node=xxxxxxxxx type=SYSCALL msg=audit(1259005528.146:1202): arch=40000003 syscall=102 per=400000 success=yes exit=1 a0=11 a1=1c41d60 a2=0 a3=0 items=0 ppid=1 pid=15209 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=59 comm="chromium-browse" exe="/usr/lib/chromium-browser/chromium-browser" subj=unconfined_u:unconfined_r:chrome_sandbox_t:s0 key=(null) ############################# SELinux denied access requested by chrome-sandbox.

Yes those are new and are fixed in -48 which I hope to release to updates-testing today.
