Red Hat Security Advisory: nspluginwrapper security and bug fix update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1459 Final 1 1 2012-11-13T13:58:00Z Current version 2012-11-13T13:58:00Z 2012-11-13T13:58:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-11-13T14:07:02Z Updated nspluginwrapper packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. nspluginwrapper is a utility which allows 32-bit plug-ins to run in a 64-bit browser environment (a common example is Adobe's browser plug-in for presenting proprietary Flash files embedded in web pages). It includes the plug-in viewer and a tool for managing plug-in installations and updates. 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 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. (BZ#869554) All users of nspluginwrapper are advised to upgrade to these updated packages, which upgrade nspluginwrapper to upstream version 1.4.4, and correct these issues. After installing the update, Firefox must be restarted for the changes to take effect. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2012 Red Hat, Inc. All rights reserved.
