Description The Hermit 2007-08-20 12:28:36 UTC
Description of problem:

The /usr/lib/firefox- application attempted to change the
access protection of memory on the heap (e,g., allocated using malloc). This is
a potential security problem. Applications should not be doing this.
Applications are sometimes coded incorrectly and request this permission. The
SELinux Memory Protection Tests web page explains how to remove this
requirement. If /usr/lib/firefox- 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 against this package.

Since there are insufficient details provided in this report for us to
