MozillaFirefox was updated to 10.0.1 to fix critical bugs and security issue.
The following security issue has been fixed:
CVE-2012-0452: Mozilla developers Andrew McCreight and Olli Pettay found that ReadPrototypeBindings will leave a XBL binding in a hash table even when the function fails. If this occurs, when the cycle collector reads this hash table and attempts to do a virtual method on this binding a crash will occur. This crash may be potentially exploitable.
Firefox 9 and earlier are not affected by this vulnerability.
