selinux now causing trouble with seamonkey

[Antonio Olivares]

Dear all,

In addition to the bug filed 
https://bugzilla.redhat.com/show_bug.cgi?id=432198

selinux now is causing trouble with seamonkey.

I deleted the ~/.mozilla/ directory and started from
scratch.  So the argument about the plugins will not
work now :)

Am I the only one seeing this?
I feel kind of bad about complaining that selinux is
doing this, but it did not happen before and now it
does, both with firefox and with seamonkey.  

Here's the message

Summary:

SELinux is preventing seamonkey-bin from making the
program stack executable.

Detailed Description:

The seamonkey-bin application attempted to make its
stack executable. This is a
potential security problem. This should never ever be
necessary. Stack memory is
not executable on most OSes these days and this will
not change. Executable
stack memory is one of the biggest security problems.
An execstack error might
in fact be most likely raised by malicious code.
Applications are sometimes
coded incorrectly and request this permission. The
SELinux Memory Protection
Tests
(http://people.redhat.com/drepper/selinux-mem.html)
web page explains how
to remove this requirement. If seamonkey-bin does not
work and you need it to
work, you can configure SELinux temporarily to allow
this access until the
application is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Allowing Access:

Sometimes a library is accidentally marked with the
execstack flag, if you find
a library with this flag you can clear it with the
execstack -c LIBRARY_PATH.
Then retry your application. If the app continues to
not work, you can turn the
flag back on with execstack -s LIBRARY_PATH.
Otherwise, if you trust
seamonkey-bin to run correctly, you can change the
context of the executable to
unconfined_execmem_exec_t. "chcon -t
unconfined_execmem_exec_t
'/usr/lib/seamonkey-1.1.8/seamonkey-bin'" You must
also change the default file
context files on the system in order to preserve them
even on a full relabel.
"semanage fcontext -a -t unconfined_execmem_exec_t
'/usr/lib/seamonkey-1.1.8/seamonkey-bin'"

The following command will allow this access:

chcon -t unconfined_execmem_exec_t
'/usr/lib/seamonkey-1.1.8/seamonkey-bin'
