Description Suraj Prasad 2010-02-15 17:56:23 UTC 
Summary:

SELinux is preventing /usr/libexec/plugin-scanner "execstack" access.

Detailed Description:

SELinux denied access requested by plugin-scanner. It is not expected that this
access is required by plugin-scanner 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.

Comment 1 Daniel Walsh 2010-02-16 16:30:09 UTC 
Miroslav, could you add



tunable_policy(`allow_execstack',`
	allow xguest_t self:process execstack;
')
