Bug 656856

Summary:

SELinux is preventing /bin/bash "signal" access .

Detailed Description:

[sandboxX.sh has a permissive type (sandbox_web_t). This access was not denied.]

SELinux denied access requested by sandboxX.sh. It is not expected that this
access is required by sandboxX.sh 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
report.

#============= sandbox_web_t ==============
#!!!! This avc is a constraint violation.  You will need to add an attribute to either the source or target type to make it work.
#Contraint rule: 
allow sandbox_web_t sandbox_xserver_t:process signal;
