Description

Mozilla Firefox is an open source web browser. XULRunner provides the XUL

to crash or, potentially, execute arbitrary code with the privileges of the user
running the Firefox application. (CVE-2010-2755)

All Firefox users should upgrade to these updated packages, which contain a
backported patch that corrects this issue. After installing the update, Firefox
must be restarted for the changes to take effect.
