Description ultima.ratio.regum69 2009-12-22 16:17:36 UTC

Résumé:

SELinux is preventing /usr/lib64/chromium-browser/chromium-browser "execstack"
access.

Description détaillée:

[chromium-browse a un type permissif (chrome_sandbox_t). Cet accès n'a pas
été refusé.]

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.

Autoriser l'accès:

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.

Comment 1 Daniel Walsh 2009-12-22 17:19:04 UTC

You can add these rules for now using

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

Fixed in selinux-policy-3.6.32-62.fc12.noarch
