Low: nspluginwrapper (SL6)

Synopsis: Low: nspluginwrapper security and bug fix update
Issue Date: 2012-11-13
CVE Numbers: CVE-2011-2486

It was not possible for plug-ins wrapped by nspluginwrapper to discover
whether the browser was running in Private Browsing mode. This flaw
could lead to plug-ins wrapped by nspluginwrapper using normal mode
while they were expected to run in Private Browsing mode. (CVE-2011-2486)

This update also fixes the following bug:

* When using the Adobe Reader(tm) web browser plug-in provided by the
acroread-plugin package on a 64-bit system, opening Portable Document
Format (PDF) files in Firefox could cause the plug-in to crash and a
black window to be displayed where the PDF should be. Firefox had to
be restarted to resolve the issue. This update implements a workaround
in nspluginwrapper to automatically handle the plug-in crash, so that
users no longer have to keep restarting Firefox.

This will update nspluginwrapper to upstream version 1.4.4.

After installing the update, Firefox must be restarted for the changes
to take effect.
